2021 Annual Clinical Assembly of Osteopathic Surgeons



2021 Annual Clinical Assembly

After careful consideration of the health and safety conditions for holding a large-scale event in Orlando, Florida, the ACOS Board of Governors made the difficult, but responsible, decision to cancel the in-person 2021 Annual Clinical Assembly of Osteopathic Surgeons (ACA) and convert it to a virtual format, to be launched in early November. Please click here to see the full message from American College of Osteopathic Surgeons President Eugene W. Laveroni Jr., D.O., FACOS, DFACOS.

Offering educational programming across six surgical disciplines (cardiothoracic and vascular, general, neurological, plastic and reconstructive, proctological, and urological), the ACA is the trademark conference of the American College of Osteopathic Surgeons.
