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 have two sons; Kian was born in 2004 and Cavanaugh in 2009. When I’m not at school, I am attending soccer or baseball games with my boys.
