Tammie Yoakum

Owner/Center Director
Hello, my name is Tammie Yoakum, and I few up in Glendale with my sister/co-owner, Betsy. Before I started working in the center fulltime, I had a 30-year career in the premium finance industry. I was blessed to have that career, but Mathnasium is a ton more fun. The best part of being at Mathnasium is to see the "aha" moments and to see a students confidence grow. When I'm not working, I like spending time with my family and friends. I also love music, movies, reading and traveling.

Lan Quan

My name is Lan Quan and I have been a homeschool teacher for the past 20 years. I graduated from Arizona State University with a Bachelor's degree in Electrical Engineering and worked in the semiconductor field as a test engineer. In my free time, I enjoy growing organic vegetables in my garden as well as learn how to make healthier meals. My husband and I are blessed with four children that we decided to homeschool. I taught them math from elementary to high school level and they all received high scores on the SAT. I also taught a SAT math prep course for the Fountain Hills Christian Home Educators group. Throughout two decades of homeschooling, I've seen that every student learns math differently according to their learning style. It will be my honor to join the Mathnasium team to help students conquer and master all levels of mathematics.

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.
