Our Team

Dr Timothy Brown and his dog Levi

Dr. Timothy Brown, DVM

Owner and Veterinarian

Dr. Brown was born in Brooklyn, NY and grew up in Northwest New Jersey. After college he attended medical school until realizing his heart lay in working with animals. Dr. Brown matriculated at Ross University School of Veterinary Medicine and did his clinical rotations at the University of Minnesota. After graduating, Dr. Brown practiced general veterinary medicine and surgery for 5 years in New England. He then elected to do an intensive emergency and critical care internship at the Veterinary Specialty Hospital of the Carolinas in Cary, NC. Upon completing his internship Dr. Brown practiced emergency medicine and surgery for two years. Dr. Brown acquired Setauket Animal Hospital in 2013, and has been renovating, modernizing, and growing it ever since.

Dr. Brown brings to Setauket Animal Hospital a vast knowledge of small animal veterinary medicine. His years of general practice coupled with his time at an advanced specialty hospital and experience practicing emergency medicine, make him a well-rounded and progressive doctor.

In his free time, Dr. Brown enjoys spending time with his family, including his rescue pups, Levi and Mia, and two rescue cats, Blessing and Jasper.

Sherwood Cooper Veterinarian at Setauket Animal Hospital

Dr. Sherwood Cooper, DVM


Dr. Cooper was born in Greenport, NY and attended Southold High School. He earned his undergraduate degree from Florida State University and graduated from Ross University School of Veterinary Medicine with honors. He has owned two of his own veterinary practices and has a passion for cellular and molecular biology, pathophysiology, and surgery.

In his free time, he enjoys boating, fishing, clamming, woodworking, beachcombing, and nature walks.

Dr. Patricia Clark Veterinarian at Setauket Animal Hospital

Dr. Patricia Clark, DVM


Dr. Clark has always lived on Long Island and is currently enjoying the "empty nest" life here in Setauket with her husband, "the other Dr. Clark", and their assorted pets. The fur family these days includes a Brittany Spaniel named Finn and three, crazy, tuxedo cats.

Dr. Clark is a graduate of the Cornell College of Veterinary Medicine. Both her husband and daughter are also veterinarians; her son felt that it was enough just to own some pets and pursued his other interests. Dr. Clark's passions include traveling the world, all things Disney, and running (although recently this may have segued more into walking fast). She has run many marathons and half marathons over the years and has a wall full of "bling" to prove it!

Of course, veterinary medicine has always been her number one passion, with a special interest in soft tissue surgery. She enjoys private practice life because of the long-term relationships formed with her clients, their pets, and the opportunity to help pet-parents learn how to keep their pets healthy and around for a long time!

Dr. Julianne Gerbino Veterinarian at Setauket Animal Hospital

Dr. Julianne Gerbino, DVM


Dr. Gerbino is a Long Island native from Port Jefferson. She was an All-American field hockey player at Adelphi University where she received her bachelor’s degree in Biology in 2012. She then traveled to the island of St. Kitts to earn her DVM from Ross University School of Veterinary Medicine and completed her clinical year at Louisiana State University before returning home in January 2017.

In her free time, she likes to play field hockey, ice hockey, softball, guitar, and enjoys spending time with her friends and family. She lives with her fiancée and four cats, Chichi, Braden, Bear, and Beeker.

Dr. Mark Sibley, Veterinarian at Setauket Animal Hospital

Dr. Mark Sibley, DVM


Dr. Sibley was born and raised here on Long Island. He attended Cornell University to complete his undergraduate education and then stayed there to study at Cornell’s College of Veterinary Medicine. As a young graduate, Dr. Sibley is motivated to continue learning as much as he can from his talented colleagues. He enjoys the challenge of practicing medicine, but his passion comes from helping animals to live the longest, healthiest lives possible alongside their human companions. Dr. Sibley has particular interests in radiology, dermatology, and general wellness/preventative medicine.

Outside the clinic, Dr. Sibley spends much of his time spoiling his own animals: Nami (an energetic Corgi) and Sangha (a charming senior cat).

El Niño (who prefers to be called Niño, NeeNee, or Neen) spends his time charming the clients in the waiting room, breaking into the hospital’s pharmacy (where we store all our treats and food), and making friends with every patient (from the tiniest kitten to the largest dog). His professional interests include taste-testing new prescription diets to ensure top quality, chasing crumpled post-it notes, and a good belly-rub.
