Our tutors foster a caring, encouraging environment that helps kids thrive and learn! Read below to learn more about our talented team:

Kristen, Center Director

Kristen is a graduate of UCSD and CSUSM. She loves sharing with parents and students how targeted instruction can be life changing to our mathletes. "A few hours per week of concentrated focus and 1:1 math conversations allows strugling students to rebuild self-esteem as the content makes more sense." She loves that Mathnasium offers enrichment opportunities for mahtletes seeking rigor in their math education. 

Kristen loves math because it presents problems that can be solved. She knows math is becoming more important in society. She recognizes that it isn't about focusing on arithmetic, it is the critical thinking and problem solving. These skills are essential as students move up in their education. In working with students Kristen has noticed confidence is key when it comes to conquering math!  

Fun fact:  Kristen has two kittens who are brothers named Peanut and Taz.


Tom, Assistant Center Director

Tom is a student at UCSD and likes working with students when something "clicks." Tom has tutored for years, but the environment at Mathnasium and the Mathnasium Method, has made it a wonderful and unique experience for him. He likes the logic of math: If you follow the steps you find the answer. A teacher once said something that stuck with Tom, "Math is more like an art than a science. It is pure creation. We create answers and solutions where once there were none." This made sense to him and changed how he saw math. 

Fun Fact:  y = mx + b
