Veterinarian Team

​Dr. Jackie Fullerton

Veterinarian

Dr. Jackie Fullerton enjoys providing compassionate care for pets throughout their life stages and forming long-lasting relationships with pet owners. She likes everything from routine wellness visits and the chance to educate owners about preventative care, to tackling urgent concerns that arise, and working with owners to best manage chronic conditions.

Dr. Fullerton first came to Maine as an undergraduate at Bates College and graduated with a Bachelor of Science in Biology in 2004. She earned her Doctorate in Veterinary Medicine from the Atlantic Veterinary College at the University of Prince Edward Island in Canada in 2012. Dr. Fullerton then pursued an additional year of training, completing a small animal medicine and surgery internship at a busy emergency and specialty referral hospital outside Boston. She stayed on to work at the referral hospital as an emergency veterinarian for five years before transitioning to the primary care service for the past five years.

Dr. Fullerton grew up in a small town in Upstate New York and has also lived in Vail, Colorado for five years. She is excited to have fulfilled her dream of moving back to Maine where much of her family now lives. She now resides in Falmouth, with her husband Jake, and their two young children, Max and Avery. In her free time, Dr. Fullerton enjoys skiing, mountain biking, running and generally spending time outdoors. She also enjoys spending time with her family and friends.

​Dr. Jennifer Gamble

Dr. Gamble joins us from the Mystic, CT area, where she practiced for 17 years after graduating from Tufts University’s School of Veterinary Medicine. She grew up in Northern Virginia and obtained her bachelor’s degree and a master’s degree in Animal Behavior from the College of William and Mary prior to fleeing to New England in search of the snow she had dreamt of as a child.

As a veterinarian, she especially enjoys the relationships developed in collaborating with clients to ensure the best quality of life for their furry family members, and has a particular interest in behavior-related concerns; as a certified Fear Free practitioner, she also strives to make the veterinary experience as pleasant and low-stress as possible for each patient. Outside of work, Dr. Gamble enjoys eating, cooking, hiking, camping, and practicing Muay Thai kickboxing. She and her wife, a veterinary anesthetist, have been fortunate over the years to have shared their home with an array of animals including a crazy Coonhound, an exuberant Lab mix, a graceful calico, a personable white kitty, and a pair of charismatic wiener dogs.

​Dr. Michelle Cook

Veterinarian

Dr. Michelle Cook enjoys practicing the full art of veterinary medicine by using evidence-based medicine and compassion to provide the best care for pets and their families. She particularly enjoys dentistry, geriatric medicine, preventive medicine, and internal medicine.

Dr. Cook earned her BA at Colby College before earning her DVM from The Ohio State University and MPH from the Colorado School of Public Health. She is grateful to live, work, and play in Maine with her family.

Dr. Kerri Whittemore

Veterinarian

Dr. Kerri Whittemore is originally from Saint Cloud, Minnesota, and fell in love with Maine when she came to pursue her undergraduate degree in Biology at Saint Joseph’s College. After earning her degree in 2004, she embarked on an adventure over the pond to the University of Glasgow Faculty of Veterinary Medicine, where she completed her Bachelor’s of Veterinary Medicine and Surgery in 2009. Coming back to Maine was always her goal and in 2011, she ventured back to practice in Boothbay for about 6 years. Missing the city life, she relocated to Cumberland Foreside and joined the Falmouth Veterinary Hospital team in May 2017.

‘My favorite part of veterinary practice is helping to educate owners about preventative and wellness medicine, especially dentistry.’

Dr. Whittemore lives in Cumberland Foreside with her husband Brian, her twins Iona and Charles, and their cat, Jeffrey. In her free time, she loves cooking, knitting, travelling and spending time with her family.

Dr. Oonagh Wack

Veterinarian

Dr. Oonagh Wack enjoys surgery, ophthalmology cases, pocket pets, and the ability to have long term collaborative relationships with clients and pets to make the lives of pets’ and their people better.

Dr. Wack grew up in Canada and earned her Bachelors of Science from St. Francis Xavier in Nova Scotia and her veterinary doctorate from Atlantic Veterinary College on Prince Edward Island. She furthered her veterinary education as an intern in small animal medicine and surgery at the Western College of Veterinary Medicine in Saskatoon. The Maine lifestyle and the opportunities afforded in our state are what drew her back to Maine. She joined Falmouth Veterinary Hospital in 2005.

Dr Wack is married to John Keating, a veterinary pathologist working within the medical device industry. Drs. Wack and Keating have an extensive family including four dogs, four cats and four tanks of fish. The pets have a medley of Rockstar names including Georgie Harrison, Iggy Pop, and Waylon. In her free time, she loves gardening, kayaking, traveling, live music and hiking with her dogs.

Dr. Hillary Parlin

Veterinarian

Dr. Hillary Parlin worked as a veterinary technician for about four years and gained valuable insights into both large and small animal medicine prior to becoming a veterinarian. She spent a couple years at a Portland small animal practice and later moved onto the large animal team at Tufts School of Veterinary Medicine. She then stayed at Tufts to pursue her doctorate in veterinary medicine.

The Farmington native extended her animal science training to include a 6-month stint in Zanzibar. If you get the chance, ask her about some of her favorite African animals, including the Oxpecker (that funny bird who sits on the back of elephants).

Dr. Parlin joined us after working at a small animal practice in York, Maine, for several years. She also worked at the emergency clinic in that area.

‘I liked being able to fix things on the spot in the emergency center and rising to an immediate challenge – yet I want to work where I can develop long-term relationships with clients and pets as well. Ideally, I also wanted a practice with several other doctors on board where we could share the tough cases and learn from one another. I feel fortunate to have found all this here in Falmouth.

Internal medicine, ophthalmology, and cardiology are among Dr. Parlin’s professional interests. When not a work, you’re apt to find her enjoying a hike, sports, travel, cooking or just spending time with her family. She shares her home with husband, Cole, their young children, Glendon and Lida, plus a hound named Kevin.

Dr. Laurence O’Hara

Veterinarian

Dr. O’Hara grew up in North Wales in the United Kingdom, and he received his Bachelor’s in Biological Anthropology in 2000 from Cambridge University, Gonville and Caius College in the UK. He then earned his Vet MB with a Special Merit in Veterinary Surgery in 2003. He started his career as an equine vet, and after several years in practice, he went to the Royal Veterinary College in London to undertake a residency in Equine Surgery. He subsequently realized that his main love was small animal practice, and he returned to exclusively small animal practice whilst in the UK. His wife is from Millinocket, and after spending several summer vacations in Maine together, they decided that this was where they wanted to live and raise their family. He joined Falmouth Veterinary Hospital in March 2015 and became a partner in 2018.

Laurence O’Hara has a particular interest in surgery and leads our laparoscopic surgery service, but loves all aspects of general small animal practice.

Dr. O’Hara lives in Falmouth with his wife, Toni, and their sons Geoffrey and Oscar. He enjoys trail running with his two dogs, Chewbacca and Dilly. In what is left of his spare time, he enjoys skiing, boating and playing the guitar.

He completed a veterinary internship in internal medicine and surgery at the Southern California Veterinary Referral Hospital in Irvine, California. He knew after veterinary school that he wanted to return to Maine, so in 2006, he moved back and joined Falmouth Veterinary Hospital.
