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 full time, I had a 30-year career in the premium finance industry.

When I'm not working, I like spending time with my family and friends. I also love music, movies, reading and traveling.

A perfect learning environment.
