Tammie Yoakum

Hello, my name is Tammie Yoakum, and I grew 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.

Math is a tough subject for many, but I'm here to make it the universal language to all. In my free time, I love to draw/create art, and hang out with family and friends.

Kevin Donnellan

Hello, My name is Kevin and I am a Northern Arizona University graduate. I majored in math since it was always the subject that I found to be the easiest, aside from science.

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.
