Erik St. Louis, M.D.

I really enjoy seeing patients in the Mayo Clinic Health System Southwest Wisconsin campus, as a native of the great state of Wisconsin. I am dedicated toward bringing the best diagnosis and treatment options to each of our patients in a relatable, understandable and highly individualized manner.

Outside of work, I enjoy travel, family and outdoors activities, and music.
