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.

Drew Hollen, DO
Dr. Drew was raised in Hoquiam, WA where his interest in medicine blossomed while studying biology and shadowing local surgeons in high school. Maintaining an awareness of life’s value and brevity, he is passionate about equipping his patients with evidence-based information to help them maximize their health span and lifespan—physically, emotionally, and spiritually.
Growing up, he worked on his grandparent’s ranch, held a paper route, and went on many mission trips to Mexico. He went on to major in Spanish, then worked as an ophthalmic technician and scribe before attending medical school. He chose a broad-spectrum family medicine residency with built-in spiritual care and international medicine instruction, during which he enjoyed practicing medicine in rural Papua New Guinea and Kenya. He is a proud husband and father of two. He enjoys family fun, biblical studies, guitar, Duolingo, rowing, and biking or hiking in nature.
