Michael Parsons, DDS
Chief Surgical Officer
He studied Oral and Maxillofacial Surgery at the Medical College of Georgia. There, he specialized in maxillofacial reconstruction, facial trauma, general anesthesia, bone grafting, and dental implants. He also completed a fellowship in Cleft Lip and Palate Surgery at Dankook University in Seoul, South Korea.
Dr. Parsons is:

- A Fellow of the American Association of Oral and Maxillofacial Surgeons
- Past president of the St. Louis Society of Oral and Maxillofacial Surgeons
- An evaluator for the State of Missouri in office-based anesthesia
Dr. Parsons built his practice from the ground up, growing it to six locations throughout the St. Louis area.

Now, through Oral Surgery Partners, Dr. Parsons brings his team of experts and the systems they’ve developed to other oral surgeons like himself.
When he’s not in surgery, Dr. Parsons fills his free time with activities he loves. On weekends, he’ll go fly-fishing, boating, or hiking with his lovely wife, Georgia. He’s also a private pilot.
