Our Veterinarians

stoughton vetsRon Buffman, DVM, Co-Owner

A Dorchester, MA native, Dr. Ron Buffman describes himself as the "typical kid" who would bring home bird nests, orphaned squirrels and chipmunks — among other things. For Dr. Buffman, his love of helping animals comes from a deep reverence for both their stoicism and how they respond to being helped.

"I am always amazed at how [animals] seem to know you're helping them even at the worst times," he observes. "Unlike people, animals seem to be able to tolerate a lot of pain in their lives. People tend to complain about every little ache, unlike animals who just seem to want to have a good life. Overall, I know it sounds corny, but I think I have one of the best jobs on the planet."

Dr. Buffman earned his bachelor's degree in animal ecology from Iowa State University and his Doctorate of Veterinary Medicine from Iowa State University College of Veterinary Medicine. He is a member of the American Veterinary Medical Association, the American Animal Hospital Association, and the Massachusetts Veterinary Medical Association. Dr. Buffman's special interests include cardiology and internal medicine. He has been working at Lloyd Animal Medical Center since 1991.

Outside work, Dr. Buffman enjoys windsurfing ("my primary passion"), mountain biking, rollerblading, hiking and a good movie. He also recently earned his pilot's license and goes flying whenever he has the chance. His cat's name is Taz.

stoughton veterinarianArthur Mallock, DVM, Co-Owner

Dr. Arthur Mallock joined Lloyd Animal Medical Center in 1986 and since that time has been using his expertise and skill to do what he finds most rewarding about practicing veterinary medicine: "Being able to determine why a beloved pet is sick and then being able to make him or her well again."

Originally from Brookline, Massachusetts, Dr. Mallock graduated cum laude from Brandeis University with a bachelor's degree in biochemistry. He earned his Doctorate of Veterinary Medicine from the University of Florida College of Veterinary Medicine. He is a member of the American Veterinary Medical Association and has a special professional interest in otology (the study of ear disease). An experience early in Dr. Mallock's career demonstrated how important this branch of medicine can be.

"During my first year in practice at Lloyd Animal Medical Center, a patient was presented to me for a second opinion," Dr. Mallock remembers. "The dog had been tentatively diagnosed with a brain tumor. My examination revealed that although a brain tumor was a possibility a more likely diagnosis was an infection of the inner ear. I treated the dog with antibiotics and the dog quickly had a full recovery and lived happily for another 10 years."

Dr. Mallock is married to Tina, a registered nurse, and together they have two sons, Ben and David. The family cares for a cat named Kitty, a chinchilla name Chachi and a snake. In his free time Dr. Mallock enjoys golfing and traveling with his family. He is also an active member of his synagogue.

Dr. Kristen Blumenstock's childhood in Cooperstown, NY included experiences with the insects and small animals usually brought into the house by her family's cats that others were too afraid to handle.

Dr. Blumenstock graduated magna cum laude from Mount Holyoke College with a bachelor's degree in biology. She earned her Doctorate of Veterinary Medicine from Cornell University College of Veterinary Medicine and joined Lloyd Animal Medical Center as an associate veterinarian in 1994. She is a member of the American Veterinary Medical Association and her areas of professional interest include surgery and acupuncture.

stoughton vetsJoyce Clark, DVM

Not many people — not even many veterinarians — can say that they performed a caesarian on a horse in the middle of a field but Dr. Joyce Clark can. While growing up in Vermont, Dr. Clark had a pet pig named Spot that slept with a teddy bear and played with her family's dog. She also had a rabbit named Hopper who roamed free in the yard and would scratch on the back door to come into the house. Before becoming a veterinarian, Dr. Clark volunteered at both large animal and small animal hospitals and at the Indianapolis Zoo.

Dr. Clark earned her bachelor's degree in zoology from the University of Vermont and her Doctorate of Veterinary Medicine from Oklahoma State University College of Veterinary Medicine. She is a member of the American Veterinary Medical Association and her professional interests include exotic pets, nutrition, surgery and preventive medicine. She especially appreciates "the day-to-day challenges and variety that comes with treating different kinds of animals" and sharing her knowledge with our clients.

At home, Dr. Clark has two Boston Terriers, Nate and Ava, a cockatiel named P.J. and two Bourke's parakeets. In her free time, Dr. Clark enjoys gardening, photography, travel and outdoor activities.'

Kimberly Dinan, MS, DVM, CVA, CCRP, CVH

Dr. Dinan received her Doctor of Veterinary Medicine degree from Ohio State University in 2008. After graduation, she completed a small animal internship at two large specialty hospitals in the greater Chicago area. Dr. Dinan is a certified veterinary acupuncturist and herbalist and completed her training at the Chi Institute, a world-renowned institute for Traditional Chinese Veterinary Medicine. Following her acupuncture certification, she has also completed an advanced acupuncture course and a course on evidence based Chinese medicine. Dr. Dinan is a certified canine rehabilitation practitioner and completed her studies at The University of Tennessee College of Veterinary Medicine.

Dr. Dinan enjoys the challenge of working with clients to develop an integrative plan to treat patients with acute and chronic disease. In particular, she enjoys working with patients with neurologic or musculoskeletal injuries to help develop a plan for a complete recovery. The combination of rehabilitative medicine and alternative modalities with conventional care can enhance healing by stimulating the nervous system, modulating the immune system, decreasing pain, improving blood flow, and reduce recovery time.

Dr. Dinan is a native of New England and enjoys spending time with her husband, daughter and son, as well as their black lab, corgi, and cat. When she is not at work, she enjoys spending time outdoors running, hiking, rock climbing, and scuba diving.
