Why I chose to practice in Muskegon

I chose to work in Muskegon because of the people. In our residency program, the environment is highly collaborative and team‑oriented. Faculty across disciplines work together to care for patients and to teach residents, and that collegial atmosphere makes Muskegon a wonderful place to learn and to practice. I’m also grateful for colleagues who invest time and compassion in one another’s development, making our residency truly amazing.

Hobbies, Personal Interests, etc.

Outside of work, I stay active and spend lots of time with my family—whether I’m on my Peloton, running, hiking, or skiing. When I’m not out and about, you’ll usually find me relaxing with my beloved Australian shepherd.

Why I chose to practice Grand Rapids/Muskegon...

It's a wonderful community to live and work. Good work life balance options right outside your door. Still affordable and very close to everything. The pathology you are exposed to and will manage will prepare you for any fellowship or practice in the country.
