    “Dr. Ron”, as he is known by his patients and their parents is a Bay Area native with over 24 years of experience in pediatric medicine. He attended the University of California - Berkeley, earning a Bachelor of Science degree with honors in molecular biology and obtained his medical degree in 1992 from the School of Medicine at the University of California - San Diego. He completed his pediatric residency at Kaiser Medical Center in Oakland. Shortly thereafter, Dr. Ron spent three years in Japan providing pediatric care for United States Military and diplomatic families stationed abroad. Prior to medical school, he worked for the American Red Cross where he established and carried out health education directives for the greater community.

    Dr. Ron provides comprehensive medical care for infants, children and adolescents, acting as their primary care physician. His goal is to partner with his patients and their parents to provide comprehensive quality care working closely with each family to ensure that the child is developing and maturing properly. He strives to achieve the common goal of a healthy lifestyle for his patients and help parents with the difficult, but fulfilling task of parenting. Dr. Ron has a special interest in adolescent medicine.

    Dr. Ron currently lives on a vineyard in Cloverdale, California, where he and his wife Patricia grow cabernet sauvignon wine grapes commercially, raise sheep, tend chickens and keep a large garden, including an orchard of various fruit trees. He is an active parent in the lives of his twin children and values tremendously the time he shares with them. Dr. Ron believes that having a strong parent-child relationship is the best practical training he could receive as a pediatrician.

    During his free time, he enjoys traveling, winemaking, cooking, sculpting, art appreciation and community volunteering.
