Dr. Peter Williams, MD
Podiatry
Serving since 2023

I practiced podiatric medicine and surgery in San Antonio for almost 40 years, retiring one year ago. I have been married for 43 years and have 4 grown, married children and many grandkids. My father was a physician in San Antonio for many years and always volunteered his time, in the name of Jesus, to help folks who didn't have access to healthcare and i have followed his example.  More importantly, the Lord expects us to serve one another and retirement does not mean that stops.  I strongly believe I am a Christian who happens to be a doctor, not a doctor who happens to be a Christian.
