What do you like about working at University High School?

I am thrilled to be a part of the University High School community. University’s small size allows me to get to know each of my students on a personal level and helps me build meaningful relationships with them. University is a great place to work because we have a knowledgeable, motivated, and dedicated faculty. I feel supported by my colleagues and administrative staff.

Personal Information

I live in Zionsville with my partner and two sons. In my free time, I enjoy cooking and experimenting with different recipes. I am passionate about science education and work part-time as the Director of Communications for the American Modeling Teachers Association and as an Associate Editor for the online peer-review journal, ChemEdX.
