Dr. Zack Smith Voted One of San Antonio’s Top Pain Management Physicians in 2025

Dr. Zack Smith, recognized as one of San Antonio’s Top Doctors in 2025 for Pain Management, standing with award badge.
San Antonio Magazine January-February 2025 cover featuring Top Doctors, including Dr. Zack Smith as one of the 502 best physicians in San Antonio.

In a list recently published by San Antonio Magazine, Dr. William Zachary Smith was voted a Top Pain Management Physician by his peers in the San Antonio area.

Using an online survey, San Antonio Magazine solicited peer nominations from physicians in the greater San Antonio area, asking them to nominate up to three doctors per practice area they would trust with their medical care or the medical care of their family. To ensure the nomination process is peer-based, doctors were asked to limit their nominations to physicians whose work they’ve personally witnessed. San Antonio Magazine then tallied the results, selecting the top percentage of vote recipients in each practice area before submitting the final list for fact-checking, which includes a review of good standing among medical boards.

Dr. Smith is honored to be included in this list alongside his talented peers in Pain Management and other specialties.

Dear Painsmith Patients,

It has been a pleasure caring for all of my patients over the past several years here in San Antonio. Unfortunately, due to ongoing personal health issues, I will be unable to continue caring for you with the same high level of care you are used to. Because of this, my last date treating patients at Painsmith will be September 5, 2026.

If you have a scheduled appointment prior to this date, we are more than happy to keep that appointment, and will attempt to accommodate other patients who wish to be seen prior to our final date. If you wish to cancel your appointment please contact the office.

Your medical records will remain at Painsmith, and we are happy to forward your records to yourself or a physician of your choosing. Our office staff can assist you with forwarding or obtaining your records. Additionally, we are currently in discussions with other local area pain physicians who have expressed interest in assisting with your care moving forward. If we locate a physician with both capacity and capability to deliver the same quality of care, we will provide an update at that time.

Thank you,

William (Zack) Smith, MD
