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.

Rob Donelan

Center Director

Rob is a lefty from the golden buckle on the wheat belt in Kansas, and has been working with students in Mathnasiums for more than 7 years. He enjoys puzzles, computers, and math as well as gardening and sports in his spare time. He has been involved in education most of his adult life as a classroom teacher, coach, counselor, administrator, and parent.

Math always strikes Rob as a giant puzzle and he likes the answers to make sense. Helping and watching others develop this joy thrills him, so he do this for work, and it is not a chore to him!

Favorite Math Joke: 7 is an odd number. How can you make it even? Answer: remove the S.

Interesting Facts: Rob loves numbers. He has slept in all 50 states, visited over 30 countries, has spoken 4 languages fairly well, has had 6 dogs over his lifetime, has worked in over 20 schools, played 4 varsity sports in college, and firmly believes there are 12 months with 28 days.

Alissa Robbins

Assistant Center Director

Alissa is a current undergraduate student at University of Maryland, Baltimore County and she is working towards getting her bachelor’s degree in Mathematics. Math was always one of her favorite subjects in school growing up, but when she started her first Algebra course, she knew it was something she wanted to do for the rest of her life!

Alissa loves teaching math because the possibilities are, quite literally, limitless!

Alissa loves teaching secondary education mathematics, so anywhere from 7th grade and beyond. Around middle school, students have a good structural base of the basics of math (addition, subtraction, etc.) so now it's time to build on the knowledge they have and expand their horizons!

Favorite Math Joke: Teacher: "What's 2n plus 2n?" Student: "I'm not sure, that sounds 4n to me!"

Interesting Fact: If she wasn't a Math Major, she would be a Music Major! She plays the flute and guitar and took several electronic music and music theory courses in high school and early college.

Cassie Murphy

Sales Team

Cassie is a middle school math teacher by day and a longtime team member here at Mathnasium center by night! She attended University of California-Riverside and received a B.S. in Math for Teaching Secondary School. She is a mother to the two most wonderful children and enjoys spending her time off exploring with them.

Favorite Number: 222 (the time her son was born 2:22pm)

Favorite Math Joke: Why can you never trust a math teacher holding graphing paper? They must be plotting something.

Interesting Fact: She was born and raised in Southern California but she first moved away from California just before she started at Mathnasium!

Paige Nolan


Paige is a very accomplished rising Junior at Damascus High School. She loves science and math and hopes to go into the field of astrophysics in the future. She also plays basketball for her school and has been playing the sport since second/third grade! Paige loves teaching math because not only does she understand it at a deep level, she loves it when others understand it as well. When she teaches and her student is able to fully understand the concept, it is a great feeling for both of them!

favorite subjects to teach in math are fourth grade math (because it's such an important turning point), and algebra I!

Favorite Math Joke: Why was 6 scared of 7? Because 7 8 9

Interesting Fact: I have a pretty decent jump shot in basketball (she's being very humble! Her jump shot is fantastic!)

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.
