Our Leadership Team
YEars of expertise At your service
Michael Parsons, DDS
Chief Surgical officer
Dr. Parsons is OSP’s CSO and has a practice of his own: Midwest Oral Maxillofacial & Implant Surgery. Having received his dental doctorate from the University of Missouri-Kansas City, School of Dentistry, he completed a residency at Medical College of Georgia.
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:
- Diplomate in the American Board of Oral and Maxillofacial Surgery
- 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. As the practice grew, he learned how to “take back his specialty” by hiring a team of business development experts. Together, they perfected the administrative and marketing side of the practice. With his team in place, he was freer to do the work he loved best.
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 things he loves. On weekends, he’ll go out fly-fishing, boating, or hiking with his lovely wife, Georgia. He’s also a private pilot. His ability to fly allows him to serve as a volunteer for Wings of Hope, a non-profit organization that arranges free air travel for medical purposes.
Cory is the operations “quarterback” who works with—and advocates for—OSP’s physicians. He oversees nearly every day-to-day aspect of our doctor’s practices, making sure they all have what they need to focus on their specialty. He also works closely with CFO Gary Weller on mergers and acquisitions.
Cory graduated from Southeast Missouri State with a master’s degree in business administration, emphasis in healthcare administration. He also obtained his CMPE (Certified Medical Practice Executive) designation through the American College of Medical Practice Executives.
Dr. Parsons recruited Cory right out of college to work for his practice, Midwest Oral and Maxillofacial Surgery. He’s served as Practice Administrator ever since.
During his time at Midwest Oral Surgery, he’s helped grow the practice from two locations to six—from a staff of only about a dozen to nearly eighty.
Cory and his team have built systems and procedures to allow their doctors to thrive. Now, he leverages all of these tools to help grow oral surgery practices around the US.
Cory is married—he and his wife Ann Marie have two sons. He spends his free time keeping up with his sons’ extra-curricular activities.
Cory and Ann Marie are strong supporters of their local church as well as the Adoptive Care Coalition of St. Louis.
Chief Financial Officer
As our CFO, Gary handles all of OSP’s accounting, financial reporting, credit, and risk management. Partnering with Cory Welker, Gary is extensively involved with mergers and acquisitions and the integrations thereof. Additionally, our HR and IT departments report to Gary. He works closely with HR director Amanda Lefebvre to ensure OSP employees have top-notch benefit plans.
Gary graduated from the University of Central Missouri with a BSBA with a major in Accounting. His first job out of college was with Price Waterhouse where he specialized in acquisitive manufacturing, retail, banking, and healthcare clients.
Through the next phases of his career, Gary mastered overseeing the merger and acquisition process while in general management, financial and operational roles. He learned how to take businesses and help them scale quickly and profitably through a combination of great decisions and solid systems.
His experience extended through his work with several organizations, including private equity and private equity backed companies where he led the organizations growth and eventually through very successful sales and IPOs.
Now, as the CFO of Oral Surgery Partners, Gary helps oral surgeons become more profitable while scaling up. His passion is for physicians: To help them grow their practices without sacrificing their quality of life—or the quality of their work.
He and his wife Beth have one daughter and two sons. In his free time, Gary enjoys spending time with his family, playing golf, hunting, fishing and skiing.
