As a doctor with St. John’s Mercy, I appreciate being part of a team that delivers the best medical care available anywhere in the world right here, close to home.” Jennifer Scheer, MD, FAAFP, Family Medicine, 573-764-3311 Dr. Scheer is a family doctor and member of the St. John’s Mercy Medical Group.
