Lori Kim (Retired)

Center Director
I was the Center Director at Mathnasium of South Costa Mesa. Prior to opening the Mathnasium Center, I have worked in finance and commercial real estate. I received my BA in Anthropology from the University of California at Berkeley. I started this Mathnasium journey when I first discovered that my second child was struggling in math but didn't want help from her own mother. I enrolled her in a local Mathnasium and found the Mathnasium Method to be critical in my daughter's foundational understanding of math. Witnessing this in my own child I am passionate about teaching other children of all ages how to make math make sense. I believe every child has the ability to be successful in math and would like to extend our program to the community of Costa Mesa and Newport Beach.

Our Mathnasium Mission

Teach children math so they understand it, master it, and love it. Math can change their lives, and they can change the world.

What I love about Mathnasium is the ability to teach problem-solving skills and make math make sense, while also making a student smile.
