Rye Harrison Veterinary Hospital

Meet Our Team

We're so pleased to introduce you to the veterinarians of Rye Harrison Veterinary Hospital!

Gary Yarnell

DVM & Founding Partner

“We want our clients to experience the joy of the human-companion animal bond.  It is our goal to provide the best possible veterinary care to our patients at all times and to make our clients an active part of the treatment team.”

In 1977, Dr. Gary Yarnell graduated from the distinguished New York State School of Veterinary Medicine at Cornell University (Ithaca, NY), one of the nation’s most competitive; he was one of the school’s youngest ever graduates. Driven by his passion for the field, he was able to complete his undergraduate studies at Cornell in two-and-a-half years with a Bachelor of Science degree, and was then immediately accepted to its Veterinary College. As the culmination of his lifelong dream, Dr. Yarnell purchased what is now the Rye Harrison Veterinary Hospital from Dr. Howard Harmon in 1980. At the time, the practice consisted of one part-time and one full-time veterinarian, with a support staff of four. Building a reputation as a skilled and caring doctor, Dr. Yarnell was available to his patients and their owners 24 hours a day, seven days a week. Since its very first year, the practice under Dr. Yarnell’s leadership experienced a rapid and sustained growth. Today it employs six veterinarians and a support staff of 28 individuals in a modern, state-of-the-art facility.

Ever since a standard poodle joined his family when he was a young boy growing up on Long Island, Dr. Yarnell had dreamed of becoming a vet. While he excelled academically, he also worked hard during summers and school vacations to acquire real hands-on work experience with animals, including cleaning cages at the local veterinary hospital, mucking out stalls and assisting equine vets at a horse farm, and even walking a pet goat through Central Park as part of the New York City Department of Parks & Recreation’s Zoo Mobile. Dr. Yarnell and his wife Laurie, a journalist, have lived in Rye since 1981. They have two children—Nikki, an actor/singer and licensed massage therapist (nikkiyarnell.com and massagebynikkiyarnell.com) and Adam, a Brown University graduate who is serving in the Peace Corps in Panama. Fortunately, Gracie, their yellow Lab, and Chloe, their equally adorable rescue dog from Tennessee, keep their nest from ever feeling empty.

John Pisciotta

DVM & Partner

“With compassion and commitment we directly affect the quality of life of our patient, thus supporting the quality of life of our clients.”

Dr. John Pisciotta is one of the nation’s leading experts on exotic pets, a category that includes everything from baby turtles to boa constrictors. At RHVH, more than 50 percent of his patients are exotics, many referrals from other veterinarians, bird clubs, and breeders. Fascinated with exotic pets since his childhood on Long Island, he grew up with a vast variety of them, including snakes, turtles, tortoises, frogs, lizards, birds, ferrets, guinea pigs, mice, rabbits, and other pocket pets. This fascination with animals led to his first job, conducting tours for a local park.

After completing his undergraduate education at Muhlenberg College (Allentown, PA) and graduate studies at Purdue University (West Lafayette, IN), he served an internship at the renowned Animal Medical Center in Manhattan and became an active member of the Association of Avian Veterinarians. Having shared quarters with so many different species of animals throughout his life, Dr. Pisciotta feels very comfortable handling, examining, and discussing the proper care of all exotic pets. A major interest of his is educating people about the needs of these very special pets. Because preventative medicine is so important with exotic and other pets, he helps his clients learn as much as possible about their basic care, nutrition, and husbandry. Dr. Pisciotta lives in Croton-on-Hudson with his wife Stephanie, their four children, and an assortment of cats, dogs, birds, and exotic fish.

After graduating in 2008, Dr. Green worked as an associate veterinarian at a small animal hospital in New Jersey for two years. She then completed an internship in avian and exotic medicine and surgery at Maryland’s VCA Veterinary Referral Associates, where she received specialized training in birds, reptiles, and small exotic mammals. With an interest in avian/exotics, dentistry, and pathology, Dr. Green joined the practice in 2011.

Following time spent as a veterinary technician at Oradell (NJ) Animal Hospital, he attended Ross University School of Veterinary Medicine in St. Kitts, fulfilling his clinical coursework at Louisiana State University (Baton Rouge, LA). Upon graduation in 2008, he completed a small animal medicine and surgical internship at the Veterinary Emergency and Referral Group (VERG) in Brooklyn, NY, after which he worked at two VERG associated hospitals in Brooklyn. Dr. Fabiano joined RHVH in May of 2014.

After veterinary school, she completed a small animal rotating internship in medicine and surgery at Cornell University. Since finishing her internship in 2013, Dr. Livingston worked primarily in emergency medicine before joining Rye Harrison Veterinary Hospital in 2018. She is looking forward to transitioning to general practice and having the opportunity to develop long-term relationships with her patients and the people who love them.

 Dr. Sperling says the best part of working in the veterinary field is creating a strong foundation to prevent behavioral and health problems in puppies and kittens and helping owners make informed decisions to improve their pet’s well-being.

Dr. Sperling currently shares a home with her Miniature American Shepherd, Parker, who she competes in obedience and agility. In her free time, she enjoys reading and hiking.
