Konstantinos Spaniolas, MD — Academic Profile

Bariatric surgery is a life-changing process for patients. My involvement in the Stony Brook Bariatric and Metabolic Weight Loss Center affords me the opportunity to work on a well-coordinated multidisciplinary team and provide cutting-edge bariatric care. Furthermore, I enjoy doing health services and outcomes research, primarily targeting bariatric surgery in high-risk populations.
