Paul Williams, MD

Dr. Williams spent 8 years during his formative years in Taiwan and India watching his father, a Family Physician in Centralia for over 30 years, making a difference in people’s lives. It was because of this experience and his own experiences in medical school, that he went into Family Practice. Dr. Williams finds great satisfaction in helping people through all stages of life in dealing with their health concerns, and enjoys seeing the whole family and being part of his patient’s lives over the years. His sensitivity to his patients’ struggle with the affordability and accessibility of medical care is what drove his decision to open Washington Park Direct Care.

Dr. Williams has four sons and three daughters.
