About Our Northwest San Antonio TX Animal Hospital

Callaghan Road Animal Hospital is a family-oriented husband and wife team conveniently located in the western part of San Antonio, just inside Loop 410 on Callaghan Road.

After graduating from veterinary school, we spent many years working in other veterinary practices. Eventually, we were able to open our own office in November 2010 and bring our down-to-earth approach to San Antonio pets and their owners.

One of the benefits of owning our own clinic is that we are not bound by strict corporate guidelines that dictate how we treat our patients and their owners. We not only provide exceptional veterinary care for you and your pets, but also treat your pets as if they were our own. Dr. Guevara, Dr. Evans, and the entire staff at Callaghan Road Animal Hospital strive every day to provide quality, compassionate care for your pets while keeping your costs at an affordable level.

Our commitment to the community extends far beyond the constraints of our hospital walls. In an effort to do our part in controlling the growing animal overpopulation problem, we are proud to volunteer with numerous rescue organizations and animal shelters. We also have had the pleasure of helping many pets find their forever homes. Visit our Facebook page to see some of our recent adoption success stories. Our Callaghan Road Animal Hospital family grows more and more each day, and we’re thrilled to have you as a member.
