Lauren D. Tully, DVM
Dr. Tully joined our team in 2019. Born and raised in Brooklyn, NY, she tried to satisfy her early love of animals by feeding the neighborhood stray cats and starting a dog walking business.

Dr. Tully earned her Bachelor of Science degree and her DVM degree at Cornell University. After graduation, she completed an internship in Equine Medicine at a private practice in Charlottesville, Virginia. She then went on to complete a residency in small and large animal anesthesia at the Ontario Veterinary College in Canada.

Just prior to coming to SWTVMC, Dr. Tully worked as a senior emergency clinician at The Emergency Pet Clinic of San Antonio. Although she still enjoyed the challenges and rewards of emergency medicine, the overnight hours and commute from her home in Sabinal were becoming less desirable.

Dr. Tully lives in Sabinal with her husband, 2 children, dog, cat, goats, horses, and has a small herd of cattle.
