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 is active in his community, and serves as a Medical Director for both the Davita Grass Valley and Auburn facilities.  He has served as Sutter Auburn Faith Hospital’s Vice Chief of Staff, and 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,  and 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 a ten provider practice that can serve a much larger patient population and geography while maintaining the same commitment to excellence and individualized patient care.
