June 27, 2012

Gregory Sirounian, MD, an orthopaedic surgeon specializing in complex adult hip and knee replacement and revision surgery, has recently joined Winthrop-University Hospital’s Department of Orthopaedic Surgery as an Attending Physician.

Dr. Sirounian is certified by the American Board of Orthopaedic Surgery and is Fellowship-trained, having performed over 250 joint replacement procedures annually for the past several years.

Raised in the Pacific Northwest, he received two undergraduate degrees, a Bachelor of Arts in Political Science from the University of Washington, and a Bachelor of Science in Biology from Portland State University. He received his Medical Degree from the Oregon Health and Science University in Portland. After completing his orthopaedic surgery residency training at the UMDNJ-New Jersey Medical School in Newark, NJ, he pursued an additional year of fellowship training in Adult Hip and Knee Reconstruction, at the Florida Orthopaedic Institute in Tampa.

In 2002, Dr. Sirounian began his career in Arizona, where he co-founded Valley Orthopaedics, a leading orthopaedic practice in the Southwest Phoenix metropolitan area. He developed a largely specialized practice, providing orthopaedic care for thousands of patients with hip and knee arthritis over nearly ten years. As one of the top total joint surgeons in the area, he initiated the opening of two orthopaedic departments at new hospitals, built in 2003 and 2005. In 2006, he helped form Integrated Medical Services, one of the largest multi-specialty medical groups in Arizona, where his former practice still serves as the orthopaedic division.

In 2012, Dr. Sirounian relocated his family to the New York area to join Winthrop Orthopaedic Associates, where he will continue to specialize in hip and knee replacement and revision surgery. Dr. Sirounian is an Active Fellow with the American Academy of Orthopaedic Surgeons, where he volunteers as a member of the Patient Safety Committee.
