Our Dedicated Staff

Meet the People Behind the Mission

Dec. 19, 2025

Compassion drives our care. Collaboration makes it possible.


Every person at the Freeman Center brings a story—and a calling—to this work.

Many have walked beside loved ones with intellectual or developmental disabilities. Others have dedicated their careers to removing the barriers patients face every day. Together, we’re reimagining what inclusive, person-centered care can look like.

Across disciplines and departments, our team shares one goal: helping each individual we serve feel seen, respected, and empowered. Whether coordinating complex care, offering behavioral health support, or guiding families through transitions, we work side-by-side to improve lives in meaningful ways.

This is more than healthcare. It’s a shared mission of equity, access, and human dignity. Get to know the people who make it happen.
