Sonoma Valley Hospital

Guy Delorefice, MD

Dr. Delorefice (or Dr. Guy as most patients refer to him) has been practicing in Sonoma County since 1999 and is board certified in Internal Medicine.

He first dreamed of becoming a doctor at the age of five. He attended St. Mary’s College of CA where he received a degree in biology and then went on to attend Creighton University for medical school where he received his MD degree. While at Creighton he took advantage of the opportunity to set up medical clinics in third world countries and became fluent in Spanish. He did his internship and residency in Internal Medicine at Providence St. Vincent’s Medical Center in Portland, OR.  

After he finished his training in 1999, Dr. Guy moved to Sonoma County to be near home and family. Since then he has worked tirelessly building a great reputation in Sonoma County and was voted by his peers as a top physician in his specialty in 2016 and 2017.

As of January 2017, Dr. Guy took over Dr. Olness’ concierge medical practice where he and his office staff pride themselves on providing the highest level of service possible.

Dr. Guy is married to his beautiful wife, Rebecca, since 2001. He has two wonderful children, Milan and Capri. His main hobby is spending time with his family but he also loves the outdoors and a good adventure. He enjoys road biking, mountain biking, abalone diving, hunting, fishing, and skiing.

Dr. Delorefice prides himself on three simple values: Quality, Service, and Communication.
