About the Clinic
Mid Valley Large Animal Service began in a garage in Denair, CA on December 23, 1992. Founding partner Dr. Mark Brandt merged his client base with that of his vet school classmate Dr. Craig Brooks to form a practice that would provide an intensively personalized service to their clients. By summer of 1993, Mid Valley had grown to 3 vets and was renting a small office in Ceres. Dr. Brooks left with the equine portion of the practice in 1996, leaving Drs. Brandt, Ted Howze, and Bryan Morrett to tend to their ever growing dairy and beef cattle clients. The year 2000 found us in our current office on Taylor Road with 5 vets, a new pharmacy sales program, and full service milk quality laboratory. The 2005 merger with Sierra View Animal Health in Escalon brought 2 more vets and a thriving small ruminant practice. Sadly, cancer took Dr. Morrett from us in 2012. Dr. Howze retired from practice in 2015 allowing the next generation of veterinarians to attain ownership with their fresh ideas and abundant energy. Our team of veterinarians stand ready to address the ever changing service needs of our amazing clients.
