About
Care built on questions and answers
I am part of the medical team at Prevea St. Mary's Health Center in Green Bay, Wisconsin, where I provide evaluation and treatment for a wide range of inflammatory and autoimmune conditions.
My approach is relational. Good rheumatology starts with listening, so I take the time to ask questions, answer them, and build a working relationship with each patient.

Conditions
What I treat

“I work as hard as I can with my patients to try to get control of what their problem might be. It is my goal to help them get back to what they enjoy most.”
