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.
Dr. Henry Thomas, DVM
Dr. Thomas began his studies in the field of entomology, earning a degree from the University of Florida. He then went on to pursue not only his DVM from UF, but a Masters in Public Health as well. When he’s not at the clinic helping people and their pets, he enjoys spending time with his family, watching movies (he’s a Star Wars fan, and loves the sci-fi genre), playing video games, swimming and jogging. He is married to Dr. Susan Thomas and together they have 2 daughters, Aeryn and Allison. They also have 5 pets including 3 cats, Rygel, Carrot, and Chopper, and 2 dogs, Chiana and Reyna.
Dr. Susan Thomas, DVM
Dr. Susan Thomas received her DVM from the University of Florida in 2003. Her undergraduate degree, from the same university, was in Animal Biology and Equine Nutrition, so her knowledge is wide and far-reaching. The veterinary field is one she finds most rewarding, particularly the opportunity to work with people and help their pets in every aspect of their health. Out of the clinic, she enjoys reading, playing computer games and going to theme parks. She also loves anything written by Jane Austen, as well as the exciting world of Star Wars. She and her husband Dr. Henry Thomas have 2 daughters, Aeryn and Allison, as well as 5 furry kids: cats Rygel, Chopper, and Carrot; and dogs Reyna and Chiana.
