Staci Gehlbach

I feel lucky to have the opportunity to channel my love of working with children and watching them achieve success at Mathnasium. I get to spend more time in the center working along side Dan now that our kids are now both in school. I graduated from Texas Lutheran University with a Bachelors of Arts degree in Elementary Education. I have taught in school districts in Texas, Nevada, and most recently in West Des Moines.

Meg Meyer

Assistant Center Director
I grew up in Waukee, and I graduated from Simpson College with an Elementary Education degree and a Special Education endorsement. I always knew I wanted to work with kids, and I have found my home at Mathnasium. I love teaching math, because it is so fun to watch something ‘click’ in a child’s brain! Favorite Number: 25 - Because it is a perfect square and is a quarter of 100.
