Meet Our Team of Veterinarians


Dr. Chris O'Sullivan, DVM

Dr. Chris O’Sullivan was born in Franklin, Pennsylvania and is the seventh of eight children. The family moved to Sebring in 1978, where Dr. O’Sullivan developed an early interest in science, nature, and animals. His first job in the veterinary field was in college, working for Dr. Anderson at what would later become Oak Hammock Animal Hospital. Dr. O'Sullivan received his bachelor's degree in Microbiology from the University of Florida after transferring from South Florida State College. He earned his Doctor of Veterinary Medicine degree from the University of Florida College of Veterinary Medicine in 2000. 

After graduating, Dr. O'Sullivan worked at Cobb Animal Clinic in Greensboro, North Carolina for four years before spending eleven years at Veterinary Healthcare Associates in Winter Haven, Florida, a large 24-hour animal hospital. It was while he was working in Winter Haven that he met his wife Tara. Dr. O'Sullivan returned home to Sebring in 2016 when he and Tara purchased Oak Hammock Animal Hospital from the retiring Dr. Anderson. 

Dr. O'Sullivan enjoys the relationships he builds with clients and their pets and hopes that when he is able to help an animal, he is helping their family. During his free time Dr. O'Sullivan enjoys traveling with his friends and family, reading, flying private planes, tending to his aquarium, and all things Florida Gators. He and Tara have a large freshwater aquarium full of Discus Fish named after characters from Game of Thrones, as well as a Chihuahua mix named Mr. Big, a black Labrador Retriever named Mac, and two cats named Zumaya and Pudge.
