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

Center DirectorDoreen Thi, Center Director

Doreen earned her B.A in Mass Communication from Campbell University, North Carolina. She also earned her Master of Education from Regent University. She is very passionate about education and loves working with kids of all ages. Growing up, she has always enjoyed math yet fully understand the challenges students may face in math learning, especially if there is a gap. The great mathematician and philosopher Alfred North Whitehead made a point that although we are often urged to make a habit of thinking about what we're doing, the precise opposite is the case. Civilization advances by extending the number of important operations which we can perform without thinking about them. Likewise, students must know math facts automatically so that they don't have to calculate simple sums or products each time they are needed in a larger problem. Whether your child is advanced or in need of working with a Berkeley Lake math tutor for homework help, here at Mathnasium, we have a team of math experts to help your children boost his/her mathematics skills and move forward in school.
