R. August Ritter III, MD
Accepting New Patients!
Dr. Ritter is a Southeast Missouri and Cape Girardeau native. He is married with 6 children and 7 grandchildren. He enjoys horses (and playing polo), training herding dogs, sailing, hunting and fishing. Ritter spent 11 years in the US Army Reserves as part of the 21st General Hospital based in St. Louis, MO. He is a third-generation physician in the Advanced Orthopedic Specialists practice, which his grandfather started in 1930. He loves his work and the opportunity to care for this wonderful community.
Helping patients return to a comfortable and active life - that's what I enjoy about being an orthopedic surgeon.
