Our staff is built to teach each student individually, to develop the skills they need to thrive in mathematics, and to foster a love of learning.

Kelly Alexman

Assistant Center Director

Kelly holds a B.S. degree in Computer Science and also a M.A. in Counseling Psychology. She worked as a computer professional for 10 years, and then moved into the counseling field. While working as a counselor, she supplemented her income with substitute teaching and realized that teaching children gave her the most job satisfaction.

"I feel privileged every day to share the Mathnasium methods with students. Helping them discover their own talents and increasing their confidence in both their abilities and themselves is a daily reminder of why I love working here."

Kelly, along with her husband, Larry and their two teenage children stay busy with soccer and school activities. She enjoys bike trails and loves every season, especially fall.

Fun Facts: I am a “Potterhead”, I have read all 7 Harry Potter books many times! I have cross-stitched anything from Christmas ornaments to blankets. I have ridden the MS150 bikathon 4 times and have zip-lined down a mountain and gone white-water rafting. I would like to read a book about every President.

Dustin Snodgress

Assistant Center Director

Dustin has always had a big passion for Mathematics. He pursued the application of mathematics by obtaining an AAS in Electronic Engineering Technologies. He worked as an Engineering Laboratory Technician at a major local engineering firm for six years, and eventually as an Electronic Engineer at a manufacturing company.

Dustin never stopped attending college and worked towards a Bachelor’s degree in Mathematics. He is a member of the Mathematical Society of America.

Dustin started working at Mathnasium as an instructor in August 2014 and fell in love with the Mathnasium way. He believes learning math is more than just learning arithmetic. Learning math also trains the brain in deductive reasoning, thinking constructively, and problem solving. This can be seen as students who attend Mathnasium often see improvements in other subjects as well.

Dustin loves disc golf as a past time and also mountain biking (his dog loves running along!). “While the wonders of mathematics amaze my mind the most, I'm also a fanatic for physics, enthusiastic about the universe, and crazy for the cosmos.”

New fun facts about Dustin: I landed a 180 backside boardslide on a rail, rotating to a frontside, dismounting with a 180, completing a 540 rotation in total. (What was that again?) Every winter, I build 2 quarter pipes with a fun box & rail for a small backyard terrain park.

Goal: To continue to get better at math. I am studying the Mathematics behind Einstein's Theory of General Relativity and also Quantum Mechanics to help understand Life, The Universe, and Everything. (42)

Matt Krambeer


I have always enjoyed numbers and math, even from a young age. I graduated from the University of Notre Dame, where I studied math, philosophy, and theology. In the future, I hope I will always be able to work in an environment where I can use my math skills. I like Mathnasium because everyone here is very friendly, and enthusiastic about math!

Favorite Number: the golden ratio which is approximately 1.618, symbolized by the Greek letter phi. I like this number for its many interesting mathematical properties, and also because it can be found in many places in nature!

Favorite math joke: Life is complex; it has real and imaginary components!

Fun facts about Matt: I want to create a game for mobile devices, I have studied Spanish, German, Japanese & Ancient Greek.

Katie Sulek


I hold a B.S. degree in Mechanical Engineering from LeTourneau University and a M.S. in Mathematics. I have spent the last 7 years working as an engineer in the aerospace defense industry. In addition to recently teaching a course at a local university, I am working towards becoming a certified secondary teacher. My dream job is to teach Math at an International school somewhere in SouthEast Asia. I love Mathnasium because it gives students a safe place to challenge themselves and grow.

Fun Fact about myself: I love to travel and have been to every continent. (Yes, even Antarctica.)

Favorite Math Joke: Parallel lines have so much in common.... it's a shame they'll never meet.

Favorite Number: 60. I love that it was used as the base for the ancient Mesopotamia number system and has endured to this day as our base for measurements of time.

Mac Feldmann


I am senior at Prairie High School. I am currently in AP Calculus BC and am on the Academic Decathlon Team. Additionally, I am on the Prairie Basketball Team. I love Mathnasium because I am passionate about math and want the next generation to be passionate about math as well.

My favorite number: Graham’s number.It is the largest number ever used in a mathematical proof. It would cause a black hole if you were able to comprehend it.

Favorite Math Joke: Why do Calculus Majors never throw house parties? Because you should never drink and derive.

In five years I will most likely be getting a masters degree in physics and genetics.

Jackson Alexman


I am a senior at Linnmar Highschool. I participate in Soccer and Cross Country.

I applied to Mathnasium because I enjoy teaching/helping people and math. I appreciate that Mathnasium strays away from traditional techniques by teaching on a case-by-case basis. Mathnasium allows for expansion and divergence where standard schooling is restricted to a curriculum. In five years, I hope to be going to a college for either a teaching or computer science degree.

Favorite number: My favorite number is 2^3, in congruence to Octagons, my favorite shape.

Favorite Math Joke: Why did the math book go to therapy? It had too many problems.

Fun facts about Jackson: During digital learning, I received the best grades I ever have. In middle school, I created a document filled with bad puns that I added onto frequently. One of my favorite jokes from it goes as follows: Two guys walk into a bar. The third one ducked.

Reagan Stock


Hi my name is Reagan and I am a senior at Washington Highschool taking AP Calculus. I participate in band, cross country and track. I plan to go to college for some sort of engineering degree. I like Mathnasium because it helps a wide range of people in an encouraging and fun learning environment.

Math joke: PLAN (P+L)(A+N) PA+PN+LA+LN ......Your plan has been foiled

Favorite number: 6 because it’s divisors are it’s sum. (1+2+3)

Fun fact: I can solve a Rubik’s cube. I play 5 instruments, guitar, piano, clarinet, saxophone and ukulele.

Meredith Beer


Hi, my name is Meredith and I’m a junior at Xavier High School. In my spare time enjoy reading and play the saxophone. I am currently taking Calculus. I love Mathnasium because it not only teaches you math but also builds your confidence in math and in other subjects and activities as well.

Fun Fact: I was a student at Mathnasium for 7+ years!

Favorite Math Fact: The fibonacci spiral appears almost everywhere in nature: flowers, shells, storm patterns, and even in your face!

Evie Hansen


Hi, my name is Evie and I am a junior at Kennedy high school. I enjoy playing instruments such as the bassoon, saxophone, and flute. In five years I hope to be furthering my education in engineering or the medical field. I love Mathnasium because students can learn at their own pace and are rewarded for their hard work!

Favorite number: Zero

Favorite math joke: Why can’t a nose be 12 inches long? Because then it would be a foot

Fun Fact about me: I have hundreds of pets! I own reptiles, fish, beetles, roaches, and a dog.

Halas Wilson


My name is Halas Wilson. I'm a student at Mount Mercy University studying for a mathematics degree. In some of my time at Mount Mercy I have done research on the relationship between math and music. I have one more year until I graduate.

One thing I like about Mathnasium is the wide range of Mathematical content that is taught

Favorite Number: 2 because it no matter if you add it or multiply it to any number it gets big kind of fast.

Favorite Math Joke: When you keep missing math class it starts to really add up.

Our Mathnasium Mission

Teach children math so they understand it, master it, and love it. Math can change their lives, and they can change the world.

What I love about Mathnasium is the ability to teach problem-solving skills and make math make sense, while also making a student smile.
