Center Manager

Hello, my name is Zachary and I have been an instructor at Mathnasium of Littleton for 7 years, all the way back to when I was just 15! Besides my passionate love for mathematics & teaching the subject, I enjoy many things. Throughout the year, I play Ultimate Frisbee. 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. In my free time, I enjoy solving logic puzzles, like Sudokus or one of my Rubik's Cubes. 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.


Assistant Center Director

Hi, my name is Reyna! I have worked at Mathnasium for 6 years and I love working with our younger students. I have a degree from CSU in Human Development and Family Studies with areas of concentration in early childhood education and prehealth. My passion has always been working with children which is why I love working at Mathnasium and why I considered becoming 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 numbers 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


Center Manager

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.



Hi! My name is Conor. I earned a degree in applied math from the University of Colorado Boulder. I'm annoyed, but understanding, when people put me on a pedestal for being good at math. What I've learned for myself, and from my professors, is that being successful in math isn't predetermined at birth, but rather a result of hard work, just like any other skill. This fact, in addition to the math itself, is what I want students to learn. I want them to be able to use their mathematical abilities when necessary and learn more math if that is something they want/need to do. I was attracted to Mathnasium because of it's demonstrated success in helping students excel in math. I know what it feels like to shift from being confused by a math concept to understanding it, and want to help Mathnasium's students achieve the same feeling.

In my free time you will find me reading, hiking, spending time with my family (and dogs!), playing disc golf, and, of course, doing math! My current math project is working to understand the water waves that arise in my Nalgene bottle.


Favorite Number and Why: 3435. Because 3 3 + 4 4 + 3 3 + 5 5 = 3435.

Favorite Math Joke: Have you heard about the mathematician who is afraid of negative numbers? He will stop at nothing to avoid them!

In 5 years I will be . . . . Studying applied math in graduate school.

Fun Fact: I can solve a Rubik’s cube in under a minute. I can also solve cubes with 4, 5, 6, and 7 layers (the normal Rubik’s cube has 3 layers).



Hello! My name is Adrian and I am currently a senior at Metropolitan State University of Denver majoring in chemistry. My family is from Guatemala but I am a Colorado native. I prefer Colorado’s cool dry air to Guatemala’s hot humid climate any day.

Ever since I was a kid, math and science were always my favorite subjects in school. Math and science go hand in hand with each other because they both are used to interpret and understand the world we live in. Throughout my life I have been told by many people that I would be a great teacher as I am very kind, optimistic, and patient. It is important to me that students feel supported as they progress through their academic careers and that they learn to celebrate their successes, even the little ones. My dream job is to be a chemistry professor. I decided to work at Mathnasium because I believed it could give me valuable teaching experience. Working with a variety of students of all ages has helped me to be creative and find new ways of explaining academic topics.

Favorite Math Joke: Why did the mathematician spill all his food in the oven? The directions said, “Put it in the oven at 180°”

In 5 years I will be . . . . In graduate school pursuing a masters degree in physical chemistry.

I love Mathnasium because . . . . . Of the support system. I really value the care and effort Mathnasium puts towards creating a comfortable judge-free learning environment. I love helping students build their confidence in math and make them feel supported.

Hobbies: I love games! Video games, board games, card games, you name it! When I’m not playing games, I enjoy going to the park to walk my dog. In summer, I enjoy hiking and going on camping trips with my family.

Favorite Math Topic and Why: I really enjoy taking derivatives of functions. The concept came easy to me and it was my favorite thing to do in Calculus. Partial derivatives are fun too!



Hello my name is Jacob, I graduated from Colorado School of Mines with an undergrad degree in statistics in 2020. I have recently moved back to Colorado and am pursuing a masters degree online through the University of Florida. One of my goals is to help make math more accessible to people in their everyday life, and I believe that being a part of the mathnasium team will help to accomplish this goal.

Favorite Number and Why: 42, it is the secret to everything.

Favorite Math Joke: Teller: Why was 6 afraid of 7 Listener: I don’t know Teller: Because 7 ate 9. Teller: But why did 7 eat 9 Listener: I don’t know Teller: Because it is important to eat 3 squared meals a day

Fun Fact: I was not able to snap my fingers until my Sophomore year in college.

Favorite Math Topic and Why: Probability, it helps us to predict likelihood of events before they happen



Hi! I am Madison and I am a student at CU Denver. I am moving to the school of Education and Human Development next year with a goal of becoming a teacher. I have always loved playing teacher and helping my friends with their math homework since I was younger. I hope to turn this natural interest into a career in the next 5 years. The reason I came to work at Mathnasium was first, in order to pay for my college tuition and secondly, to work at a career based job. My career-based job search hadn’t been going well until I found an application for a tutoring center called Mathnasium. Suzie, our center director, reached out to me the next day. It felt like fate that I’d just stumbled across the application for a perfect job and they were so inviting. Since working here, our center director Suzie has been nothing but supportive and understanding as well as the rest of the staff. I am truly so grateful to have stumbled across a work environment that brings me so much joy and works with a college student’s schedule.

Favorite Number and Why: My favorite numbers are 814 and 1. I like 1, because I see it all of the time (111, 11:11, etc.). I see it on clocks, street signs, $$$ totals, and more. It does’t mean anything to me but it makes me smile when I see it. 814 is my other favorite number because it is the time I was born.

Favorite Math Joke: My favorite math joke has got to be the classic:

Why was 6 scared of 7?

Because 7 8 9

I love Mathnasium because . . . . . I love Mathnasium because it makes me happy to go to work. Before here, I had worked at 2 grocery stores and quite honestly dreaded walking into most shifts. When I work with the kiddos and my amazing coworkers, I always leave the building happier than when I walked in. The supportive, understanding, fun environment that has been created here is not just one for the kids and will rub off on anyone that walks into the center.

Fun Fact: A fun fact about me is that I own 116 plants. My plants are my babies and I have no intentions of stopping or downsizing anytime soon.

Hobbies: Some of my hobbies that I get to enjoy on my days off include plants, long boarding, embroidering, painting, collecting hand-made glass pendants and trinkets, collecting rocks, and lots of homework.



Hi my name is Sullivan (that's my last name but it is how I preferred to be called). I am privileged to be part of building confidence in a difficult subject. I want to foster a tenacious mindset: the belief that difficulties can be overcome with perseverance. I believe that mindset will serve students well throughout their lives, even beyond the realm of math. I liked math in middle school, but my high school did not have a good math program. I knew I needed a high SAT score to get into my college of choice, so I studied on my own. I often wished I knew someone who could help. After college, I noticed my friend Zach would always come back from work with an interesting story, energized by a passion for teaching. I thought: hey, I'd like to teach math too!

Favorite Number and Why: My favorite number is 60 because it can be neatly divided so many ways: it has 12 factors, and the first six factors are in sequence: 1, 2, 3, 4, 5, 6. This is why we use it for measuring time. The number 72 is also good, but not as good.

Favorite Math Joke: There are three kinds of people in this world; those who can count, and those who can't.

What are your dreams? I want to design tabletop role playing games (like Dungeons & Dragons): create imaginative spaces where people can strive and play as avatars of their best selves.

In 5 years I will be . . . . A published Board Game Designer



Hi! My name is Loghan and I’m a junior at Colorado Academy. I play soccer and field hockey for my high school and love to enjoy the beautiful Colorado outdoors. I chose to work at Mathnasium because I enjoy the fun and supportive environment and the opportunity to spread my love of math. It is very rewarding to me when I witness a moment of understanding from a student after struggling with a problem or topic. I know this experience firsthand and hope to encourage other students to embrace the challenge that math can bring. My elementary school math teacher instilled my love for math and always pushed me to deeper understanding. Although challenging sometimes, it was a rewarding experience, and I consider her a role model. I hope to be a role model for students just like my teacher was to me!

Favorite Number and Why: My favorite number is number 2 because it has been my uniform number in soccer since I was 5 years old.

Favorite Math Joke: How do you keep warm in a cold room? You go to the corner. It’s always 90 degrees!

In 5 years I will be . . . . In college pursuing some type of STEM degree.

Hi! My name is Vishnu, and I am currently a senior at D'Evelyn Jr/Sr High School. I was born in Colorado, so naturally, I love all the Colorado activities. I mountain bike and hike in the summer and enjoy snowboarding in the winter. I have done karate and boxing in the past, and I ran cross country and played volleyball for my school. I like playing games of pickup football with my friends and watching the Broncos during the football season. I want to study chemical or aerospace engineering in college. My love for mathematics is what brought me to Mathnasium.

Favorite Number: I love the number seven because it just looks like a perfect odd number.

I love Mathnasium because . . . I have always enjoyed mathematics, and I want to help others improve their skills. I want others to enjoy learning math as much as I do.

Favorite Math Topic: My favorite day of math class was when we learned the derivative of e^x.

Why did you come to work at Mathnasium? My sister worked at Mathnasium in the past, so I already knew a little bit of what Mathnasium was about. As I was looking for a job, I decided Mathnasium would be the perfect place to hone in my basic math skills while helping others gain a strong foundation in mathematics.



Hello! I’m Nathaniel. I’m a Junior at Lakewood High School and I also attend math classes at Colorado School of Mines. I’m on the LHS swim team as well as Pi Club (my school’s math club). I have always enjoyed math and science and the way that they are used to understand and harness the world around us. I came to work at Mathnasium to extend my love of math and support for kids, but also because of the constant fun and loving environment Mathnasium has. I want to keep contributing to learning and help kids understand that just because something is difficult, doesn’t mean it is impossible to master. In fact, it is extremely rewarding! Math isn’t just about numbers, but also about the problem-solving process used throughout life. In college, I want to study physics or machine learning. Both are very interesting to me and I still have a lot of time to choose.

Favorite Number: My favorite number is 2 because of its use in computing. In binary, there are 2 fundamental states (off and on/0 and 1) and powers of 2 are very important when working with computers.

I love Mathnasium because . . . math has always been my favorite subject and I wish for every student to see the beauty and fun in math. Mathnasium does exactly this in a supportive environment that builds kids’ confidence.

Hobbies: I love swimming, hiking, and playing pickleball as well as spending time with friends and family. I also enjoy playing board games because of the critical thinking and problem solving that they involve.

Favorite Math Topic: I love Calculus because of its use in science and to solve real-world problems. Calculus also introduces a whole new way of looking at math.



Hi! My name is Jason, and I'm an upcoming Senior at ThunderRidge High School. I'm part of the football team, and love being outdoors and staying active. I decided to apply at Mathnasium because it seemed like the perfect place for a first job. I have never had any trouble with math in school, and being an older sibling as well as helping my mom run her at-home daycare has given me experience working with kids. I thought why not put my talents to use making a positive difference in a child's life instead of flipping burgers in a greasy kitchen? While working here at Mathnasium, my primary goal is obviously to teach math to students and deepen their understanding of math. However, I hope that while teaching these students can develop an attitude of perseverance that will help them not only in math but for the rest of their lives.

Favorite Number: 1 is my favorite number because it's the only positive integer that's not a prime or composite number.

Favorite Math Joke: What do baby parabolas drink?

Quadratic formula.

In 5 years I will be . . . Pursuing a degree in Physics or Engineering

Favorite Math Topic: While it wasn't easy to learn, calculus was my favorite math topic because it has interesting and useful applications in physics.



Hello, my name is Makenzie Sobieski! While looking at jobs for over the summer, I remembered seeing Mathnasium near my local high school, Columbine. I thought, “How cool would it be to help kids be as passionate about math as I am”. I have always been better at Math than English, so I decided this job would be a perfect fit for me. After shadowing other Mathnasium employees, I realized how awesome the atmosphere and culture at Mathnasium was and knew I had to take advantage of the opportunity. I think my favorite part about being an instructor is seeing the vast improvement in not only kids’ math skills, but also their love for math. Math can be a very tricky subject, but once understood, it is sure to be a favorite.

Favorite Number: My favorite number is 7 because it has been my softball number for my entire 10-year career and it is also my bunny, Phoebe’s, birthday.

Favorite Math Joke: Question: Why did the obtuse angle go to the beach?

Answer: Because it was over 90 degrees.

In 5 years, I will be . . . Graduated from the Colorado School of Mines with a Civil or Biomedical Engineering degree.

Hobbies: Competitive softball, hiking and traveling with my family, and spending time outdoors.



Hello! I am Ariana and I am a sophomore at D'Evelyn Jr./Sr. High School. In elementary school, I struggled with English as a second language, so math immediately became my favorite subject because it is globally taught and understood. Mathnasium is a very welcoming place where I love to spend time working with different kids and help them improve their math skills. In my free time, I like going to the mountains, dancing at my studio, and spending time with friends. After high school, I plan to study some sort of engineering in college.

Hobbies: Snowboarding, drawing, dancing, listening to music.

Fun Fact: I speak three different languages.

In 5 years I will be . . . traveling throughout Europe.

Favorite Number: I like the number 8 because it is an infinity sign flipped.



Hello! I’m Carol Wall and I’ve been a private math tutor for 12 years, including 2 years as a private teacher for two competitive skiers in Vail, Colorado. I received a degree in marketing and advertising from Michigan State University, but always had a passion for numbers. I worked as a media buyer negotiating contracts for television and radio, and then as an account executive managing budgets. When 2 of my children were diagnosed with learning differences, I took time off from my advertising career to help them navigate school. I found I had a gift for teaching math to students with dyslexia, dyscalculia, dysgraphia and other learning differences. So, I started my own tutoring business and have been very busy for the past 12 years. I came to Mathnasium because most of my students graduated or were succeeding at math on their own. After an interview and trial day, I knew this place was for me! Getting to impact so many children’s lives by helping them make sense of numbers and understand how math is used every day in our world is very rewarding!

In 5 years I will be: Semi-retired as a math tutor and traveling to beaches around the world.

Fun Fact: I was a ski instructor while taking math and engineering courses at Michigan Technological University

Hobbies: Board game nights, Going to mountain town cabins to hike, explore and have campfires, swimming at our neighborhood pool in the summers, and trail riding on our three horses, Bentley, Sterling and Luna.

I love Mathnasium because . . . my passion is to figure out how a student learns best and watch them finally make sense of numbers and realize that math is a universal language.



Hello! My name is Christine and I am a sophomore at Colorado School of Mines. I study computer science and computational applied math. I am especially interested in how we can use math to improve cybersecurity. In my free time I enjoy reading, skiing, rock climbing, and just being outdoors. I am originally from New Mexico but I moved to Golden for school. I love math and most things related to math. I hope to someday have a job that lets me study math for a living.

Favorite Number and Why: e – I find it fascinating that a seemingly trivial number appears in almost every branch of science.

Favorite Math Joke: More of a limerick really: A dozen, a gross, a score, plus three times the square root of four, divided by seven, plus five times eleven, makes nine squared and not a bit more.

In 5 years I will be . . . Working on my master’s degree in computational math

What are your dreams? I hope to someday move abroad and to be able to continue studying the things that I enjoy in many different places. I would like to be a professor so I can share my love of math with others while also being able to do research on the topics that interest me.



Hi my name is Luke. I am an undergraduate student at Colorado School of Mines. I am currently studying Engineering Physics with a Minor in Applied Mathematics. I have always loved math and science, and I love helping others enjoy learning it as well. I grew up in Elko, Nevada, a place with plenty of mountains, so naturally, I love hiking, skiing, camping, and spending time outdoors. I think that being good at math isn’t s skill that your born with, but it’s something that you can get better at through practice, and hard work. I’ve struggled with math in the past, and the reason I’ve succeeded is by asking for help and trying to deeply understand the concepts. I used to be a college STEM tutor, and I was able to help student who struggled with the basics of math succeed in their classes.

Favorite Number: 52 has always been my favorite number. I don’t think there’s any specific reason. Maybe its because 5+2 = 7, the universal lucky number.

Favorite Math Joke: How do you make seven even?. . . .Take away the S.

I love Mathnasium because . . . . .I can see how impactful it is on kids’ lives. It’s always awesome to see someone who struggled at math start to excel at it.
