Our Staff

Thomas A. Fredenhagen, DVM (aka “Dr. Fred”) was born in St. Augustine, FL and raised in Palatka, FL. He attended St. Johns River Junior College and the University of Florida, before receiving his DVM degree from Auburn University in 1976.

After an internship in Tallahassee, FL he moved to the Jacksonville/Orange Park area to continue companion animal practice. He established and ran the Argyle Animal Clinic for 10 years. He has been practicing veterinary medicine for more than 40 years. He is a member of the American Veterinary Medical Association and the Florida Veterinary Medical Association. He has worked with and been a board member of Safe Animal Shelter.

Karen Fredenhagen has been a Veterinary Technician for more than 25 years. Her areas of extensive experience include surgery, special needs, nutrition, acupuncture / homeopathy (studied under Dr. Peggy Flemming for four years), behavioral counseling and laser therapy.

She also manages the staff and hospital business operations. She rescues owls, hawks and horses to name a few. Karen shows horses and has shown dogs. Karen has assisted at Safe Animal Shelter and served on the Board of Directors.

Grace joined the Kingsley Animal Hospital family in February 2015. Since then she has worked her way up from vet tech to our hard-working office manager. She has a deep love for dogs, especially boxers and pitties. 

She's volunteered with organizations such as wildlife rescue centers and the Jacksonville Zoo. Her personal zoo at home includes 2 pups: Jimi (a chihuahua/dachshund mix) and Harper (a lab mix) as well as her first ever cat, named Neo. Her other passions include binge-watching shows on Netflix, going to the beach, and keeping up with her human son.

Samantha officially joined our team in February 2017.  She graduated from the University of North Florida in 2015 with a Bachelor of Science in Biology and aspires to be a veterinarian one day.  Samantha’s love of animals runs deep, but has specific affections for dogs, cats, horses, and wolves. 

Samantha is also an avid reader of fantasy novels, collects painted ponies figurines, loves to draw using pastels and dabbles in painting and sculpting.  The household menagerie of pets includes three rescued dogs (Bella, Allee, and Treble), a toy poodle (Pearl), four rescued cats (Loki, Odin, Bandit and Othello), and her beloved German Shepherd (Denali)

Bobbie's career in vet medicine actually began in 1998 when she began working at a veterinary surgery specialist. Her passion for animals ignited during those days and the rest is history! 

Bobbie joined us in 2020 and we couldn't imagine the hospital without her caring disposition. She has an affinity for the tiny dogs especially and her own critter crew includes two chihuahuas and two kitties.

Jordyn joined us in 2022 and has learned so much since then! In her free time you can find her reading, tending to her plants, or enjoying a good movie. She enjoys outdoor activities such as hiking or swimming, especially in the summer! 

Caring for animals has been a passion of hers and being a vet tech is the first step in a life long career of animal wellness.

Errol is our Kingsley Animal Hospital emotional support cat. He was brought in as a kitten in 2021 after he'd been thrown out of a car window and run over. He required some intense hospitalization for a few weeks but he has blossomed into the best little office supervisor. 

The car incident left him with some neurological issues and he will never be 'normal' but he is imperfectly perfect to us! You may see him hanging around the hospital, napping in his window seat, or greeting humans and pets alike in the lobby/rooms.
