Our Staff

Jim Antunano, Jr.

Jim Antunano, Jr.
Practice Manager

For Jim, veterinary medicine has always been a family affair—he’s Dr. Antunano’s son! He had a pet at home ever since the day he was born, and he truly can’t remember a time when he didn’t want to do everything in his power to help all of the animals he possibly could. Jim gets to live his dream every day as the Practice Manager here at the Animal Medical Center.

Jim grew up in Westchester County, New York and worked in the state for nearly 10 years in a different career field. He started to realize he wasn’t truly happy with his work, and started to look for a new opportunity after he and his wife had their first baby. The pair moved to Florida, and Jim enrolled in college at the University of South Florida to receive his Bachelor’s degree. He relocated to the Valrico area in August of 2000 and joined his father here at the Animal Medical Center. Jim has been serving the area’s pets and animal owners ever since!

Jim and his wife, Lynda of nearly 30 years have two terrific grown sons, and they share their home with two young Dobermans: Sampson, who is just over a year old, and Sampson’s biological sister, Eva. When he isn’t spending quality time with his family and pets or helping things run smoothly here at the clinic, Jim loves to cheer on his beloved New York Yankees and Giants. Every World Series or Super Bowl win is a cherished memory!

Our Founder

Jim  Antunano

Dr. Jim Antunano, DVM

Our Founder, Dr. Antunano, “Dr. A” as he is known by both clients and the AMC team alike, started the clinic in a small storefront in 1988. His vision was to create a state-of-the-art practice that would incorporate the most up to date technology to compliment his vast veterinary knowledge and experience and make that available to all of our clients and their pets. His vision was realized when he relocated to a larger, modern facility where he was able to incorporate such things as Laser Surgery, Ultrasonography, Digital Radiography and more. The clinic has since relocated to a modern, 4000 square-foot location which has enabled us to continue in the tradition on which his vision was founded.

Originally from New York City, he began his collegiate career at Herbert Lehman College before attending veterinary school. Upon graduating, he worked as an Associate Veterinarian for several years in high-volume practices, as well as serving as the Medical Director and lead veterinarian for an Emergency and Critical Care facility in New York. Dr. A eventually decided to open his own veterinary hospital in the Brandon-Valrico area. 

Dr. A was a pioneer in laser surgery and was president of the Veterinary Laser Surgical Society in 2007. He was also a member of several veterinary associations including the AVMA, AAHA and the Veterinary Emergency & Critical Care Society. Dr A. has always had a strong passion wildlife care and has even treated lions, tigers, and bears!

He has since retired, but Dr. A’s presence will forever be felt here as we strive to continue with the tradition of providing the highest quality of care to our clients and their pets. His caring and dedication to the veterinary profession has made a lasting impression on our clients, pets and especially our staff.
