CenterDirectorChelsey Tyler, Center Director/Owner


Chelsey graduated from Texas A&M University with a Bachelor of Science in Marine Biology. She knew from a young age that she always wanted to be a teacher. After working at Mathnasium of Humble South as an instructor and Center Director for 3 years, Chelsey was given the opportunity to purchase the Center and make it her own.  The relationship with her students and the passion she had for her career, made it an easy transition. 

She loves helping kids build their confidence in math, make math make sense again, and provide help for parents struggling each night to help their kids with their homework. Chelsey has been a Mathnasium Franchisee since 2018 and she loves the idea of helping kids get ahead and stay ahead; all while making math fun again; especially for those students were "bored" in math and needed a greater challenge.  Mathnasium has hundreds of amazing success stories across the country as a result of our Passionate Instructors, the Inspiring Learning Environment, Teaching Style and Curriculum at Mathnasium! Let Mathnasium help your student today! 

MartinekLarry Martinek


Larry Martinek, Chief Instructional Officer, Developer of Mathnasium Program. 

Larry has spent his entire career finding a better way to teach math. From inner city to public schools, to acclaimed magnet schools, to leading private and parochial schools, Larry has served as both a classroom teacher and as an educational consultant. He has designed curriculum, teaching strategies, and teaching materials designed to help students and teachers learn math more effectively. He has trained teachers in the art and science of boosting student’s ability to “do” math, thereby increasing student’s math scores and feeling of self-worth. Larry is the developer of Mathnasium’s educational program – one of the most comprehensive and innovative curriculums ever produced for teaching math.

While Larry is not an Instructor at our Center, He is a valuable asset we can call on to ask about specific students scenarios for guidance and advise. This has helped to make visits more productive and enjoyable for many of our students.
