Jenna Riesterer
Center Director
My name is Jenna Riesterer, and I’m so excited to step into the role of Center Director at Mathnasium of Oconomowoc! I’m originally from Menomonee Falls and graduated from UW–Madison with a degree in Marketing and a minor in International Business. My studies gave me a strong foundation in math and analytics and a real appreciation for how math shows up in everyday life.
When I’m not at Mathnasium, you’ll probably find me reading, running (I’m currently training for the Lakefront Half Marathon), checking out a concert or musical, or traveling. An all-time favorite trip of mine was a semester abroad in Milan, Italy, a time I still love talking about whenever I get the chance.
I’m truly excited to get to know all of you and your amazing families. It’s an honor to be part of a team that helps students grow in confidence and thrive in math!
