Dr. William Harmon is a board-certified Urologist and subspecializes in robotic partial and radical nephrectomies and other minimally-invasive procedures.

As a member of the nation’s busiest kidney transplant program at the Texas Transplant Institute, Harmon is responsible for removing kidneys from healthy adult donors. Each week, he performs three to four living donor nephrectomies.

Harmon is the medical director of Urology San Antonio and established the practice’s post-doctoral laparoscopic fellowship training program. In addition, he acts as a clinical assistant professor for local urology residents, providing hands on surgical instruction.

“I praise God for leading me to Dr. Harmon. He’s an awesome person, doctor, and surgeon. My recent surgery was flawless as was my care at the hospital. Thank you Dr. Harmon and staff.” ~ TB

“A year ago I was diagnosed with renal cell carcinoma. I had malignant tumors on both kidneys. Being 69-years-old, I expected the worst. My wife wanted to take me to M.D. Anderson, but a friend of my daughter recommended that we go see Dr. William Harmon of Urology San Antonio first. Dr. Harmon discussed and analyzed my illness to the point where I could understand what was best for me. He was very charismatic, caring and easy to understand. My family and I immediately connected with him and we placed all our trust in him. He never disappointed us. I had robotic surgery on my right kidney [in April] and regular deep surgery on my left kidney on [in May]. A small portion of my right kidney was removed and as well as all malignant tumors. My recovery periods went smoothly thanks to his staff and assistants. In December, I underwent a post-surgery scan and everything came out negative. Dr. Harmon was god-sent and he will always have a special place in my heart. My family will always be grateful. Thank you Dr. Harmon for saving my life.” ~ James

“As a 45-year-old extremely healthy woman, it was so overwhelming when severe complications resulting from a [gynecologic surgery], roared into my life like an out of control train. […] With lots of encouragement, patience and endurance from Dr. Harmon, we pushed on with the various surgeries needed to fix me. […] Dr. Harmon along with his surgical assistant Mr. Michael Ball took the utmost care, time and effort required in order to piece me back together. I will never forget what happened to me, but because of the extensive knowledge, skills, the need to help others, and the shear determination to get it done, I now have had my life returned to me. Thanks so much for all you do and give.” ~ Stacey

“Dr. Harmon, it has been a year since our mom’s surgery. Mom is in good condition and in a much better mood and health than a year ago. Thank you for a successful surgery. Most of all thank you for accepting our mother as your patient at the last minute. Your friendly attitude and way of caring made my mother and our family feel very comfortable. Once again, thank you.” ~ The J. Family
