Harvey Partridge, DVM, Founder, 1946-2019
Dr. Harvey Partridge founded Partridge Animal Hospital in 2005. Raised in the small town of Mount Dora, Florida, amidst farms, ranches, and orange groves, he knew from a very young age that he wanted to be a veterinarian.
His dream came true in 1974 when he graduated with his DVM from Auburn University College of Veterinary Medicine. Four years later, he started his first veterinary practice, Riviera Animal Hospital. Prior to that, he worked as a ranch manager and studied at the University of Florida’s College of Agriculture, where he earned a B.S. in Animal Science.
Dr. Partridge was an active and passionate participant in the veterinary community and a member of the American Veterinary Medical Association, the Florida Veterinary Medical Association, and the Pinellas County Veterinary Medical Association.
A devoted family man, Dr. Partridge married his childhood sweetheart, Patricia, in 1967. They had two sons – Matthew and David – and were blessed with two grandsons, Ethan and Shane. Both Dr. Partridge and Patricia died in a tragic plane crash on October 20, 2019.
Dr. Partridge gave our hospital more than just its name. Hardworking, compassionate, knowledgeable, and patient, he made our team a family and our clinic a home away from home for countless animals and their owners. He will be greatly missed.




David Landers, DVM, Owner
Dr. David Landers, the owner of Partridge Animal Hospital, grew up in Franklin, Tennessee and was introduced to the world of veterinary medicine at the age of 13. “Our family veterinarian gave me a summer job as a kennel helper, and it opened up a new world of veterinary medicine and surgery to me,” he recalls.
Dr. Landers attended Auburn University for both his undergraduate and veterinary medicine degrees. He first earned a B.S. in Animal Sciences in 1989 and went on to graduate with his DVM in 1993. Today, he has professional interests in orthopedic surgery, ultrasound and stem cell therapy. Dr. Landers is a member of the American Veterinary Medical Association, the Florida Veterinary Medical Association, and the Pinellas County Veterinary Medical Association. Dr. Landers also holds certificates in Ultrasound, Stem Cell Therapy and Tibia Tuberosity Advancement surgery, surgery for ACL injuries.
He and his family have a golden retriever named Abby who is the clinic’s official greeter, another playfully/naughty golden retriever named Merida, a rescued Bengal cat named Nala, a snowshoe cat named Midori (green in Japanese for her green eyes), and a three-legged rescue feline named Fergus. Dr. Landers is married to Sherri, who is a commercial pilot. They are parents to Grace, who is attending Auburn University as a pre-vet major. When he’s not caring for patients, Dr. Landers enjoys photography, karate, and competitive shooting. His wildlife photography can be seen on the walls of Partridge Animal Hospital.




Mary Power, DVM
Aside from a few years at Auburn for veterinary school, Dr. Power is a true Floridian—she was born in Tampa, lived in Dade City and Land O’Lakes, and also attended college at the University of Florida in Gainesville.
Dr. Power grew up with cats and other assorted pets including a hermit crab named Sebastian. She has loved both animals and teaching since she was a child, and to this day, client education is one of her favorite aspects of being a veterinarian. She also has a special interest in pet dentistry, diagnostic ultrasound, and soft tissue surgery.
She shares her home with an exuberant, spoiled beagle named Lady. Though she doesn’t think of herself exclusively as a “dog” person or a “cat” person, Dr. Power does admit that if you show her a beagle pup, she’ll be smiling ear to ear.
When she’s not working, Dr. Power loves Friends reruns, chocolate, and traveling—she’s even been as far as the Amazon in Peru. She also enjoys sports including football, baseball, basketball, and volleyball and is an enthusiastic Rays fan, as well as any team in orange and blue (Go Gators and War Eagle!).
