Dr. Ken Simmons, DVM

Veterinary Medical Director

Dr. Simmons graduated from the University of Florida’s College of Veterinary Medicine in 1981. He established Simmons Veterinary Hospital in 1983 as a small storefront facility. His business grew into an all-encompassing Professional Pet Center, with a full-service hospital, emergency care facility, the “Barkers Hotel and Purrington Inn” and the “Pawsitively Purrfect” grooming salon. By 2015 the staff at SVH had grown to 8 full time veterinarians and 85 lay staff.

A network of 41 computers provided maximum efficiency and a virtual “paperless” environment, while presenting the client with the highest perception of value. Simmons Veterinary Hospital was profiled in Vet Economics as a “Practice of Excellence”, and has received national recognition as Impromed Inc’s “Best Place to Work”.

He retired (in a moment of profound weakness) in 2015, but has subsequently been drawn back into the Veterinary world to work with Epica™ Medical Innovations & Epica™ International as Veterinary Medical Director in charge of implementation and education and recently expanded his works with Peregrine Radiology.
