Bio
I am so excited to serve as the Registrar at Lyons Middle/Senior High School. Having lived in Lyons for most of my life (yes, I am an alumni!), I am grateful to be part of such a close-knit community. My husband and I have two children who attend Lyons High School and who are actively involved in multiple sports and school activities. As both a parent and staff member, I value the strong connections that make our small school so special. I look forward to supporting our students, families, and staff!
