Dr. Hannah Kinsella’s love for animals began at an early age. Growing up, she spent countless hours with her aunt, who cared for dogs, cats, and horses, while her parents encouraged her passion by welcoming just about every kind of pet into their home—from fish and lizards to birds, hamsters, rabbits, dogs, and cats. Caring for animals has simply always been part of who she is.

As a veterinarian, Dr. Kinsella especially enjoys building lasting relationships with pets and their families and witnessing the incredible bond they share. She believes some of the most rewarding moments in veterinary medicine come from partnering with pet parents to help their companions live healthier, happier lives.

An equine internist by training, Dr. Kinsella has a special interest in internal medicine, with additional passions for geriatric care and surgery. She enjoys solving complex medical cases while helping senior pets maintain the best possible quality of life.

At home, Dr. Kinsella shares life with her husband, their two children, a French Bulldog named Freddy, and a domestic shorthair cat named Marley. She jokes that she’d have hundreds of pets if her husband would let her! Outside the hospital, she enjoys reading, gardening, traveling, and spending time with her family.

Dr. Jessica Demers has always known she was meant to care for animals. Although she briefly explored other paths in college, it quickly became clear that veterinary medicine was where she belonged—and she’s never looked back.

A pivotal experience conducting research in the remote villages of Khon Kaen, Thailand, shaped her approach to veterinary care. There, she discovered that caring for animals is also about caring for the people who love them. That perspective continues to guide her practice today as she builds strong relationships with families, listens carefully to their concerns, and creates personalized care plans that support both pets and their people.

Dr. Demers has a special interest in point-of-care ultrasound, using this valuable diagnostic tool to quickly assess patients, guide treatment decisions, and improve outcomes. She is also deeply passionate about Fear Free® veterinary medicine, helping anxious pets feel more comfortable while working with families to develop long-term strategies that improve their pet’s emotional wellbeing and quality of life.

For Dr. Demers, the greatest privilege is being part of a pet’s entire journey—from welcoming new puppies and kittens, to supporting families through illness, and providing compassionate end-of-life care. Earning the trust of families during every stage of that bond is what makes her work most meaningful.

Outside the hospital, Dr. Demers enjoys spending time with her husband and four children, gardening, sewing, crafting, baking, and cooking. While she currently shares her home with a thriving 75-gallon hermit crab habitat, she also delights in the birds, squirrels, chipmunks, and “hop hops” (rabbits) that visit her backyard. She fondly remembers her beloved Pit Bull, Mocha, and her mischievous cats, Mylo and Allie, who helped shape her lifelong love of animals.
