About Cornerstone Pet Hospital
Caring for Pets and the Families That Love Them
At Cornerstone Pet Hospital, our mission is simple: to provide compassionate, high-quality veterinary care while treating every pet — and every family — with kindness and respect. Serving Brownwood, TX, Early, TX, and the surrounding Heart of Texas communities, we are proud to be a trusted partner in your pet’s health and happiness.
Our Story
Cornerstone Pet Hospital has been part of the Brownwood community for many years, dedicated to helping pets live healthier, happier lives. In 2022, Dr. Rebecca Barnhart and Dr. Russell Kotzur, a husband-and-wife veterinary team, acquired the practice from Dr. Jeff Windham. After years of practicing in the Dallas/Ft. Worth area and later in Abilene and Sweetwater, they felt drawn to Brownwood as the perfect place to build deeper roots for their family while continuing their lifelong passion for veterinary medicine.
Together, Dr. Barnhart and Dr. Kotzur have created a family-friendly clinic culture centered on education, preventive care, and comfort. Their philosophy is that by caring for pet owners and providing them with the necessary tools, they can deliver the best possible care for pets.
