 Raji Rayaprolu, Center Director & Owner


Hello! 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. 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!  Our family welcomes you to experience this great learning environment and we look forward to serving you!

Dawn Jarocki, Assistant Center Director

Hi, I’m Dawn Jarocki, the new Assistant Center Director for Mathnasium Round Rock. I have the privilege of supporting this open-hearted and passionate crew of math enthusiasts as they help your children to understand and love math. From the owner, Raji, to our assembly of unique, friendly and knowledgeable instructors, I could not wish for a better team!

Having grown up dyslexic and autistic, as well as having worked with the Special Ed department at Round Rock High School, I was able to help these children to not only understand math, but to also understand and appreciate their own unique way of learning.

I am a transformational life coach! Whether your child is struggling, needing a challenge or just looking for a way to rediscover their joy of math... we care and want to help! We look forward to serving your family in Math.

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."

Annie Brogdon, Lead Instructor

My name is Annie Brogdon, and I am a current senior at the University of Houston. I am an education & psychology double major and currently working towards my 4-8 math teaching certification. I originally chose math just because I generally liked math in school, but working at Mathnasium has made me feel more involved in understanding why math is so much more than just learning formulas. As a Mathnasium tutor for 3 years, I feel stronger in understanding the patterns and different methods of problem solving, and I feel passionate about empowering our students to become more confident problem solvers!
Fun fact: I have been a musician for 15 years and play 5 instruments! 

Connor Hoglund, Instructor


I was born in Illinois and attended high school in TX. Im now attending Texas A&M studying computer science. I like math because it makes sense and isnt based on peoples opinion. I like working at mathnasium because all the instructors all likeable, similar minded people and I feel Im able to help students



Yui  Ginther, Instructor

 Yui Ginther is a freshman at Northwestern University, studying French Horn Performance and Journalism. Yui likes math because it’s a way you can make sense of the world. It helps you visualize and solve complex problems. He loves working at Mathnasium because he really enjoys helping and getting to know all the students.







Vedant, Instructor

I am a Junior at Texas A&M studying engineering. I have tutored many students in Algebra I and II as well as precalculus due to being a member of NHS in high school, and have been taught to ask guiding questions to help students get the correct answer due to being in AVID for 4 years. I like math. I was really bad at it several years ago. In fact, I was so bad that I was at risk of failing the standardized tests in middle school. With help from a teacher, math suddenly clicked one day because he taught it to me the way I learn. I want to help people have the same "eureka" moment I had when math suddenly made sense.





Manju, Instructor

 I am Manju, and I am currently a senior at the University of Texas at Dallas studying biochemistry. On my free time I love to play tennis, and draw/paint. I truly enjoy math, especially teaching it, as it has so many worldly applications. I enjoy working at Mathnasium because we have such talented and friendly instructors who are dedicated to helping our students
