Suzie Shride, Center Director
Hello! I am the Center Director at Mathnasium of Littleton. I am a retired classroom teacher with a Masters Degree in Education and I am Master Certified through Mathnasium University. I have more than 3500 hours of training in the Mathnasium Method. I know first-hand the Mathnasium Method works because 10 years ago my daughter went from hating math and declaring she "just didn't have a math brain" to math being her best academic subject in high school and her saying, emphatically, "Mom! I don’t need help with math! I am good at math!" Her 100% scores on math tests proved her right! She is now a Senior at Colorado State University studying to be a early childhood or elementary teacher.
I am in the process of writing about my more than 20 years of world-wide climbing and outdoor adventures in an award-winning Young Adult series, Lucy Dakota: Adventures of a Modern Explorer. My debut novel, Rocky Mountain Beginnings won the Colorado Book Award for best YA novel in 2011. The second book in the series, Journey to Nepal, is in the works. In July 2014 I hiked 96 miles along the West Highland Way in Scotland with my sister, Alliso. It was on that trip that the idea for us to partner on a Mathnasium center in Littleton was born.
I am one of those kids who had to work at math in high school and college, and despite earning straight A's, I was a finger counter. I understand the pressure kids face to succeed at math. My wish is for every child who comes to our center to reach a point where math makes sense to them and I promise to give every student that passes through our doors the foundation they need to understand math! Who knows? They might even become crazy about math!
Fun Fact: I have climbed to the base camp of the world's highest and fifth highest mountains - Everest & Makalu and have hiked and climbed around the world!
Hobbies: Hiking, gardening, travel, animals
Favorite Number: 18 - it's my birthday and has always been my lucky number. In numerology it also has special meaning to me as it adds to 9 which is my favorite number in mathematics.
Larry Martinek, Creator of the Mathnasium Method
Larry Martinek, Chief Instructional Officer, Developer of Mathnasium Program.
Larry has spent his entire career finding a better way to teach math. From inner city to public schools, to acclaimed magnet schools, to leading private and parochial schools, Larry has served as both a classroom teacher and as an educational consultant. He has designed curriculum, teaching strategies, and teaching materials designed to help students and teachers learn math more effectively. He has trained teachers in the art and science of boosting students' ability to “do” math, thereby increasing students' math scores and feeling of self-worth. Larry is the developer of Mathnasium’s educational program – one of the most comprehensive and innovative curriculas ever produced for teaching math.
While Larry is not an Instructor at our Center, he conducts many of the training sessions our instructors and center director attend, hosts special math afternoons at our annual Mathnasium convention and is a valuable asset we can call on to ask about specific students' scenarios for guidance and advice. This has helped to make sessions more productive and enjoyable for many of our students.
The AMAZING team of instructors at Mathnasium of Littleton!
Zach Aparicio, Center Manager
Hello, my name is Zachary and I am a graduate student at the Colorado School of Mines. I have been an instructor at Mathnasium of Littleton for 6 years, all the way back to when I was just 15! I'm currently pursuing a degree in Data Science, after finishing up a Bachelors Degree in Statistics. Besides my passionate love for mathematics & teaching the subject, I enjoy many things. Throughout the year, I enjoy playing Ultimate Frisbee through the club team at Mines and being in different leagues and pickup games throughout the summer. In addition, I love to travel, whether it be to Europe, Mexico, Washington D.C., Moab or Glenwood Springs. I traveled to Mexico five years ago to help with a Habitat for Humanity project through my Spanish class at school. In my free time, I enjoy solving logic puzzles, like Sudokus or one of my Rubik's Cubes. I also enjoy challenging myself at a plethora of Math Competitions. I've always loved working with kids and have always enjoyed math so sharing my knowledge with students at Mathnasium is a perfect fit.
Favorite Number: My favorite number is 1729. There was a man named Srinivasa Ramanujan who was a famous mathematician in the early 20th century. Despite growing up in India and having very limited access to the mathematical knowledge of the time, he taught himself and was sought out by English mathematicians for his work in all fields of math. A colleague and friend of his, G.H. Hardy, visited Srinivasa in the hospital and mentioned that his taxicab number, 1729, was an unusually dull number. Srinivasa remarked that in fact, it was not. 1729 is the smallest number that can be written as the sum of two cubes in two different ways, 10^3+9^3 and 12^3+1^3. Nowadays, 1729 is known as a taxicab number for this exact reason. Additionally, the sum of the digits, 19, times its reverse, 91, gives you back 1729. These types of interesting facts that you can find for every number show the true beauty in mathematics.
Favorite Math Joke: Why do mathematicians always get Christmas and Halloween confused? Because Oct 31 = Dec 25. In base 8 (Oct), the number 31 is the same as the number 25 in base 10 (Dec or Decimal).
Fun Fact: People at school and in the Ultimate Frisbee community call me Steve due to the fact that there were two people named Zach on our high school frisbee team. I received the name Steve and the nickname has stuck ever since.
What is your dream? Living in Spain with an enjoyable career and becoming fluent in Spanish.
Reyna Felipa, Center Manager
Hi, my name is Reyna! I have worked at Mathnasium for 5 years and I love working with our younger students. I'm a senior at CSU and I am currently majoring in Human Development and Family Studies. My passion has always been working with children which is why I love working at Mathnasium and why I have decided to become an elementary school teacher after college. I may not be an engineer or mathematician but I will always be there to care for your children and help them learn and grow!
Favorite Number: 7 or 9 but I have no idea why! They have just been my favorite numers since I was a kid.
In 5 years I will be . . . . working as a kindergarten teacher
Favorite Place to Travel: Greece because it was warm and the ocean was so blue
Hello, my name is Michael. I am a graduate of the University of Colorado in Colorado Springs with a bachelors in mathematics. I have been a college tutor and have worked in an elementary school for five years. I have worked at Mathnasium for 3 years now. I wanted to work at Mathnasium because I enjoy helping people out with concepts and topics that are causing them stress or difficulty. The atmosphere and the vibe Mathnasium gave off was fun and inviting, so naturally I wanted to be a part of the team. I also enjoy working and interacting with kids. I remember tutoring and holding study sessions for a majority of my college algebra class. The experience was fun, plus it was a good feeling to be able to help my fellow classmates not be super stressed out about math. The teacher noticed I was doing these things and after the class was finished, helped me get a job as a tutor at the school's learning center. I hope to use my talents and personality in order to help students be the best they can be. In addition, I want to help them build confidence, not only in math, but in their everyday life as well.
Favorite Number and Why: 18 because it's cool (and it's my birthday)
Favorite Math Joke: Are monsters good at math? Not unless you Count Dracula.
In 5 years I will be . . . . teaching math.
Fun Fact: I used to play video games competitively.
Matt Peters, Lead Instructor
Hello, I’m Matt Peters! I received my bachelor’s degree in geophysics from Colorado School of Mines, and finished my master’s degree in computer science last year. My minor was in mathematics, so I’ve got a passion for the subject. After working at Mathnasium for two years, I have decided to pursue a career as a high school math teacher and have started the process of getting credentialed to do that! This fall I will be teaching 6th grade math at Stuart Middle School!
Favorite Math Topic: My favorite math topic is complex numbers. Once long ago, we could only think of positive integers, like 1, 2, 3… At one point, someone decided to make nothing a number, and called it 0. At another point, it was discovered that there were numbers between numbers, and called them fractions. Eventually we made the concept of numbers less than nothing, and called them negative numbers. Essentially, as time went on and knowledge evolved, we kept finding utility in expanding our numeric system. Eventually, one of the most abstract discoveries was made with i, also known as the square root of negative one, or imaginary numbers. It doesn’t seem to make sense, and yet it does because the math works out! We discovered that numbers can have both real and imaginary components. That’s what complex numbers are.
Fun Fact: I LOVE problem solving. Every day I look forward to a new coding challenge, whether it’s writing a program to efficiently traverse a binary tree to get the information I want, or figuring out how many times a word needs to be split such that there are at most 4 unique characters. One of the most important things I’ve discovered about myself is that if I don’t embrace challenge, I’m a very bored man.
Hobbies: Long-distance running and healthy eating. Also, playing difficult single-player video games! I love trying something new, failing, figuring out what I did wrong and could do better, then implementing a better course of action. Self-improvement is fun!
Helen Blake, Instructor
CONGRATULATIONS TO HELEN WHO WAS ACCEPTED TO HARVARD! WHOOP! WHOOP!
Hello! I’m Helen and I’m a senior at Colorado Academy. My sister went to Mathnasium a few years back, so the summer before my junior year, I decided to look into tutoring here. Everyone is so positive and passionate about math at Mathnasium, and I knew that I would love the atmosphere. I used to hate math a lot, but my math teachers in middle school helped me and pushed me, and with time I grew to enjoy it. Since then, I have absolutely fallen in love with math. With my passion for math, I hope to go into genetics and work as a genetic counselor or cellular biologist.
What is your favorite number and why? My favorite number is 13! I am not really sure why thirteen in particular is my favorite, but I have always had a love for prime numbers.
What is your favorite math joke? How do you stay warm in a cold room? You go to the corner because it is always 90 degrees!
Fun fact: I grew up in a military family, so I moved around quite a bit when I was younger. I’ve been to ten schools, lived in five states, and moved six times. My family decided to settle in Colorado, so this is the longest I’ve ever lived in a place (five years!)
Hobbies: I love reading and writing, and I play tennis and field hockey. My favorite books are The Book of Two Ways by Jodi Picoult and Pretty Things by Janelle Brown.
Hello! My name is Emma Carpenter and I am a sophomore at Colorado Academy. I came to work at Mathnasium because math has always been a subject I enjoy and I also really love working with kids. The community at Mathnasium is so welcoming and everyone is so enthusiastic about math. My favorite math experience was my ninth grade math class. My teacher’s teaching style was to give us problems and push us to struggle our way through them as a class. The first few classes with him I would get really frustrated because I was used to learning linearly from a textbook. However, this style of teaching soon taught me that there is no specific way to solve a problem, rather it’s all about the process and the tools that you choose to use to solve a problem. I play soccer and swim for CA and I love to draw, bake and do just about anything outdoors! In the future, I’m not sure what I want to study in college but I know that I want to pursue something in the STEM field. I am excited to be a part of Mathnasium!
Favorite Number? My favorite number is number 2 because it is the first prime number and the only even prime number.
Favorite Math Joke? I saw my math teacher with a piece of graph paper yesterday...I think he must be plotting something.
Fun Fact: I love to telemark ski in my free time.
Why did you decide to work at Mathnasium of Littleton? I learned about Mathnasium through one of my sister’s friends and it sounded really fun. Math has always been one of my favorite subjects so I wanted the opportunity to share my love and enthusiasm for math with other students.
Hello! I’m Robby Ziemian and I am a sophomore at D’Evelyn High School. I’ve always been that kid, the one who can entertain himself by graphing random equations on his calculator. When I saw the opportunity to work at Mathnasium, I jumped at it because it was a job where I could do something I actually liked. In my free time, I enjoy playing basketball and soccer and reading sci-fi books (Dune is one of my favorites). Why did I come to work at Mathnasium? For me, math is not just a stepping stone that I can use to do other things, it’s something that is important by itself, if just for the reason that it organizes our thinking. I am a big believer in logic, so math really appeals to me.
Favorite Number: Six is my favorite number because it is the first perfect number (a perfect number is the same as the sum of its divisors), and it is two threes, which is another number I like.
Fun Fact: I am the third Robert Ziemian in my family, since both my dad and grandpa had that same name.
Favorite Math Topic: Prime numbers, because once you get into the thousands, or even millions, it seems impossible that there are still numbers that cannot be divided by anything. There are all sorts of cool ways to find new, large prime numbers, such as Mersenne primes (2^x - 1) and factorial primes (x! +/- 1).
Corrianna Campbell, Instructor
Hello, my name is Corrianna. I am a junior studying chemistry at Colorado School of Mines. Growing up, I wasn’t really sure what I wanted to study because I had a lot of interests, including playing the violin, literature, art, and of course, math and science. In high school, I found that I was interested in chemistry, and part of the reason for that was because it is an applied science that has its foundation in math. Math provides elegant explanations for why matter behaves in a certain way. It is beautiful because it is both universal and specific. When I work with chemistry, I use math to explain my results and explain why atoms and molecules behave the way they do. I am very excited about working for Mathnasium because I love explaining math and I enjoy working with children. Prior to working for Mathnasium, I taught violin lessons and had the opportunity to teach English as a second language to children in Chengdu, China. I believe that developing strong math skills early helps kids feel confident and excited about problem solving, and so I am passionate about helping kids learn math!
What is your favorite number: My favorite number is 29. I like it because it is a prime number, plus it is my birthday.
Favorite Math Topic: I love algebra because it reminds me of problem solving in chemistry. Solving for unknowns using a logical and systematic approach is fun!
Hobbies: Playing violin, hiking and reading.
Fun Fact: I have hiked to the top of Pikes Peak!
Tony Adams, Instructor
Hi! My name is Tony Adams and I’m a sophomore at D’Evelyn High School. I was drawn towards Mathnasium by a desire to help people who feel anxious about mathematics by showing its applications. I love working with kids because of their genuine curiosity about the world. As Albert Einstein once said, “If you can’t explain it to a 6 year old, you don’t understand it yourself.” Mathnasium is great because it breaks down big concepts such as multiplication into many parts, each with their own worksheets, to help kids develop a deep understanding of the topic. I’ve always liked mathematics but I didn’t realize it was my passion until after my first calculus course where I understood the beauty in abstract thinking. In my freetime I like to read (mostly math books), run, and practice clarinet.
Favorite Math Topic: My favorite math topic is graph theory. It's not commonly taught in school but it's a lot of fun to study independently. The subject is a great reminder that math doesn’t have to be about numbers and equations because it can also just be about abstract thinking and ideas.
Favorite Number: I like the number 28 because it is a perfect number, meaning it is the sum of its factors excluding itself. One interesting thing about perfect numbers is that we still do not know if there are any odd perfect numbers. This is called the odd perfect number conjecture and it has been around for over 2,000 years making it one of the oldest unanswered math problems.
Hobbies: I play clarinet in the D’Evelyn marching band. I also love long distance running, my favorite distance is 10k but I’ve also run half marathons. I also enjoy spending time with friends and family.
Favorite Math Joke: Parallel lines have so much in common, it's a shame they’ll never meet!
Megan MacQuarrie, Instructor
I originally moved to Colorado to pursue a double bachelor’s in music performance and economics at the University of Denver. Although my degree path was not what I wanted at the time, it was always my dream to live in Colorado, so I moved back to Denver in fall of 2017. I didn’t know what I wanted to do, but I knew practicing math and teaching/tutoring people have always been constants in my life, so I decided to start there, and see what opportunities awaited me as I lived each day.
I started out teaching Math at the Mathnasium of Cherry Creek in 2017, and moved over to the Cherry Hills location in 2018 after truly resonating with the Mathnasium curriculum and seeing how rewarding it was to see kids progress in their learning by consistent practice and exposure to different teaching perspectives.
I eventually found some incredible professional opportunities in applied engineering, design, and construction, and I’m grateful and inspired to have found a super cool way to practice what I’m most passionate about (math and data)! I’m still in the beginning of my professional journey, but I’m currently working applying my skills to electrical systems and installations and am developing goals to phase over to engineering in the renewable energy sector. Working with electricity is something I’ve truly loved learning over the past year; it’s a crazy and ubiquitous subject that requires memorizing many mathematical methods and is applied in almost every facet of our life. Let’s see where the next year takes me!
Favorite Number: 12 – it’s the first common multiple between 2, 3, 4, and 6, which makes for easy grouping and cool symmetry. It’s also the basis of music language comprised of 12 musical notes. It’s a wonderfully balanced number!
I’ve performed concerts using 3 instruments in one song on stage!Fun Fact: I own 5 animals – can you guess which kinds? (2 cats, 1 dog, 2 toads)
Hobbies: Practicing music (classical, jazz, contemporary), Yoga/meditation, listening to music/attending concerts, skiing, cooking, ice skating, hiking with the puppy, playing video games and tabletop roleplay games (there’s nothing better than rolling dice on a Friday night with your friends!)
I love Mathnasium because . . . . . I’ve always had a passion for the language of numbers, and it’s so fulfilling and exciting to be sharing the knowledge I’ve acquired with people who may not be as exposed to mathematical concepts. Sitting around talking about numbers and how they connect is one of my favorite pastimes, and I love learning about how other people make connections with and between numbers.
Andrew Clancy, Instructor
Hi! My name is Andrew. Math was always one of my favorite subjects growing up, but I definitely struggled to stay up to speed when I started learning Algebra and Geometry. I started taking online classes, which was difficult as a kid with attention issues. However I lucked out with my teacher, Mr. Mabbott, an exceptionally patient man who helped make Geometry my favorite subject at the time. I have a Bachelor's in Communications Media, and spend most of my time improving my visual art and graphic design skills; it's a personal goal to post a minimum of one art piece a day online. When I'm not teaching or making art, I try to take advantage of Colorado's great hiking opportunities.
Favorite Number: My favorite is 12. It is the number of donuts I'm liable to consume if left unattended.
Favorite Math Joke: There are 10 types of people; those who understand binary, and those who do not.
Hobbies: I enjoy reading, creating table-top, role-playing games and watching documentaries with my documentary club. I strongly recommend the book "The Boy Crisis: Why Our Boys Are Struggling and What We Can Do About It" and the documentary "Waiting for Superman."
What are your dreams? I hope to someday support myself entirely off my art and writing, and to live abroad for at least a year while I'm still in my twenties, preferably in Germany or Austria.
Seth Patrick, Instructor
Hello! My name is Seth. I’m a graduate of Wright State University in Dayton, Ohio where I received a B.S. in Biology, and American Public University where I received an M.S. in Environmental Science. I’ve chosen to work at Mathnasium to pass on a passion for math and to help explain to students how it relates to their lives. I previously worked as a public school teacher, and enjoy working with kids. Math doesn’t have to be hard, and it absolutely does not need to be daunting - it’s all about the approach.
Favorite Number: The number 1 is my favorite number, because it is the loneliest number and could use the support.
Favorite Math Joke: Did you know that there are three kinds of people in the world? Here they are: people who can count and people who can’t. Haha! That's the same joke Matthew chose! Who'd have thunk?!
In 5 years I will be . . . . teaching math or science.
Fun Fact: I’ve ridden the three tallest and fastest roller coasters in the US.
Helen Zhu, Instructor
Hi! I’m Helen Zhu, and I am a sophomore at D’Evelyn Junior/Senior High School. Ever since I was little, I have always loved helping others, whether that be helping them better understand various concepts or even just helping them with a simple favor. I especially enjoy helping others with topics such as mathematics or science, so I found Mathnasium to be a perfect fit for me. I love how Mathnasium has a very welcoming atmosphere and how enthusiastic everyone is. Up until high school, I have always just followed the formulas when it came to math, so I always knew how to get the end result with the formulas, but I sometimes didn’t truly understand the reasoning behind the formula or why exactly a result ended up to be what it was. Once I got into high school, my math teachers explained the reasoning behind all of the formulas, and everything just clicked for me. This sparked a deeper passion for math in me, and I have been amazed by all of its interesting inner workings ever since, so I am looking forward to helping kids feel more confident in their journey with math, and maybe even spark this passion in them too.
Favorite Number: My favorite number is 24 because it’s my birthday! Also, it’s just very satisfying to me for some reason.
Favorite Math Joke: Why should you stand in a corner to stay warm? Because it’s always 90 degrees!
Hobbies: I love reading, skiing, playing tennis, and spending time with my friends and family. Also, I enjoy playing the piano, violin, and playing the flute in the D’Evelyn marching band. I also recently started playing the oboe, and I am loving it so far.
Favorite Math Topic: I really like algebra. Solving for the value of an unknown variable is very satisfying to me because of all of the logic behind it.

Collin Blackford, Lead Instructor
Hi! I'm Collin and I'm starting my freshman year at Loyola Marymount University in Los Angeles where I plan to study business. I have been tutoring with Mathnasium for two years now and really enjoy it. I had been tutoring kids at my high school when I heard about Mathnasium, and I thought it would be a perfect fit for me. First semester of my freshman year I had an 82 going into the last week of school. Because of my lowest test score being dropped and doing well on the final, my grade rose to an 89.6% and I got an "A" in the class. I learned that if you study and work hard, anything in a classroom is possible. I am also an actor. I have been acting professionally since 2014 and was Bennie Burrito in the Star Girl Movie that came out in March 2020 on Disney+. In 5 years, my dream is to be living in LA working as an actor, and if that doesn't work out, my business major will make me very hireable!
Favorite Number: My favorite number is pi because it never ends.
Favorite Math Joke: Why are obtuse angles always depressed? Because they're never right!
Hobbies: Acting, playing basketball, golfing and card tricks.
Special Note: If you caught the Disney Movie, StarGirl, you might see me.
Ethan Kopec, Lead Instructor
I'm Ethan! I am a sophomore attending Benedictine College in Atchison Kansas. I came to work at Mathnasium because a friend recommended it. The center has a great atmosphere and I love helping so many kids realize how great math can be! One of my elementary school teachers was very intense, and he somehow convinced me to stay in during lunch recess to practice math. Looking back, it's amazing what people will do with the right inspiration! I work in center when I am back home and online when I am at school!
Favorite Number: My favorite number is 5 because it works so well in math.
Math Joke: 7/5 of people have problems with fractions.
Favorite Math Topic: I love Algebra because it is always balanced and you can do so many different things to get the answer.
Math is fun with the AMAZING instructors at Mathnasium of Littleton!
