Our Story

Dr. Robert Zamorano and Dr. Barbara Petrohan met while working together in the Rio Grande Valley. They both realized that the area needed a 24-hour veterinary clinic that could accommodate dogs and cats as well as small mammals, birds, and reptiles. After months of planning and hard work, Pet Doctor 911/Animal Medical Center opened its doors in March of 2013 for full-service routine and emergency pet care. Pet Doctor 911 is located in North McAllen and serves the greater McAllen metropolitan area as well as the entire Rio Grande Valley.

Pet Doctor 911 provides state-of-the-art medical equipment for prompt diagnosis and high-quality treatment of any problems your pet may be experiencing. Pet Doctor 911 is proud to offer full-service veterinary care during extended appointment hours (7am-6pm weekdays) as well as during emergency hours (every night, every weekend, every holiday).

Pet Doctor 911 is fully staffed with veterinarians and experienced support staff on the premises 24 hours a day, 7 days a week, 365 days a year. Following the vision of Dr. Zamorano and Dr. Petrohan, everyone at Pet Doctor 911 is committed to making compassionate, high-quality veterinary care available to every pet at all times.
