Gregory Spin is the Chief Executive Officer of Summit Nephrology Medical Group. Along with Drs. Bhat and Thornton, Dr. Spin founded Summit Nephrology in 2005. He did his clinical training at UC Davis Medical Center, completing his Medical Residency, a teaching year as Chief Resident, and his Nephrology Fellowship.

He sees patients in the Summit Nephrology Auburn office, which serves patients primarily from Grass Valley, Auburn, and surrounding areas. He does hospital rounds at Sierra Nevada Medical Center, Sutter Auburn Faith, and Sutter Roseville hospitals, and sees dialysis patients at the Davita Grass Valley and Auburn Units. Dr. Spin serves as the clinical leader for a “Value based care organization” that serves close to 10,000 patients from the Central Coast of California, through the Sierra Nevada foothills. He is a strong advocate for this type of “circular economy” model that creates both better patient outcomes, and a more sustainable health care system. Dr. Spin is active in his community, and serves as a Medical Director for both Davita Grass Valley and Auburn facilities. He has served as Sutter Auburn Faith Hospital’s Vice Chief of Staff, and was on the Board of Trustees for the Live Oak Waldorf School in Meadow Vista. Dr. Spin lives in Nevada County with his wife (a Sutter Medical Group Family Physician) and has raised two children in the area. His hobbies include playing tennis and running with his wife in the Auburn Recreation area, watching movies, reading, and travel, as well as living vicariously through his children who have recently flown the coop.

He has enjoyed watching Summit Nephrology develop into the preeminent nephrology practice in the Sierra Foothills, growing from a three-physician practice to an 11 provider practice that can serve a much larger patient population and geography while maintaining the same commitment to excellence and individualized patient care.
