Karen completed her Master’s degree in 2010 and, prior to moving from Texas, served three years on her elementary school’s administration team incorporating and facilitating 21st Century learning standards.

Since opening her first location, Karen has been recognized by Mathnasium as a Top Performing Franchise Owner. Karen received the Exceptional People award in 2016 for her ability to hire and train one of the strongest instructional teams through Mathnasium. Karen has also been awarded in 2016, 2017, 2018, 2019, 2020 and 2021 for having Top Performing locations. She recently served on the Mathnasium Franchise Advisory Committee, which helps guide Mathnasium Headquarters as it makes key decisions about the direction of the company. Often our center has the opportunity to pilot new curriculum or student management systems prior to global launches, allowing us to serve our students in the best way possible.
