Raji Rayaprolu, Center Director & Owner


I am Raji, and I have a Masters Degree in Health Care Adminstration, with an undergraduate degree in Pharmacy, and studied Math with vigorous interest up to Calculus.

I have developed a real passion for teaching and education as the child of a Professor of Computer Sciences & Electronic Engineering. My father taught me that education is one of the greatest contributions we can make to society. As an adult, my source of inspiration and support is my ‘better half’,  also an Electrical Engineer. A pharmacist by profession, I know that math is very important in every child's life. Math education provides the foundation that is a stepping stone for ongoing success in life! The Mathnasium Method is very structured, yet it nurtures every child and finds a way to make learning fun! I strongly believe Mathnasium provides a wonderful way of learning math where every child has an awesome experience and develops the confidence necessary for future success. Our family welcomes you to experience this great learning environment and we look forward to serving you!


Briana Johnson, Office Manager

Briana is currently a Third Year Nursing Student at Texas A&M Round Rock with an Associate's Degree in Health Science. She enjoys learning about how Healthcare and Computer Science can be combined to improve the lives of those around us. 

Briana has been teaching Mathematics in a professional capacity for 6 years, and has been with Mathnasium since 2017. "Growing up, I watched kids struggle with math and never really receive the support that they needed to reach their full potential. Mathnasium provides that support, and allows students to flourish."

Fun fact: I know 40 digits of pi, and can play the harp.

Noah Heerdink, Instructor

Noah is a Senior at UT Austin Majoring in Mathematics and minoring in Architecture Studies and Studio Art. Noah will be starting at UT Graduate School for Architecture this year.

She’s tutored students since 2015 and engaged with a large variety of students looking to improve their math skills or get ahead. Having lived abroad in Amsterdam during her childhood and studied abroad twice in Sweden and Ecuador while at UT, she’s always gravitated towards math since it is its own international language.






Dustin Levenstein

My continuing passion for pedagogy can be traced back to my experience at UT as an undergraduate student of mathematics, 

where I was exposed to the Moore method of inquiry based learning, a particular kind of Socratic approach, and I also had the opportunity to tutor at the Sanger Learning Center. I have since gone on to get a Masters degree in Mathematics at UCLA. Upon returning to Austin,  I continue to get joy from helping young children reach their own "aha!" moments as they contemplate complex abstract ideas at Mathnasium.
