Jesse Yap, Owner/Center Director

Jesse received her BA in Management Information Systems from the University of Oklahoma in 1990. After a long and successful career as a business analyst, Jesse wanted to return to her first love—working with children and helping them become successful. Jesse is a mother of two and has a deep appreciation for education, particularly in the field of mathematics. She is especially passionate about increasing children's self-confidence and loves those "Ah-ha" moments when a child gets it! Jesse now devotes her time to helping kids and adults not only understand math, but learn to LOVE math.
