Dr. Claire Thomas DVM

Dr. Claire Thomas

Growing up on a small family farm in rural Harvard, Massachusetts, Dr. Claire Thomas began her atypical journey toward a career in veterinary medicine.  

After graduating with a Bachelor’s degree in Business Administration, she embarked on a career in customer service, followed by sales and marketing work.  Her business career began in Massachusetts and included an overseas position in Sydney, Australia.  

Upon returning to Massachusetts, she chose to start a family and remain at home to care for her two boys, along with her husband Art.  During this time, the pursuit of a new found hobby, recreational horseback riding, grew into a career of teaching. Therapeutic horseback riding instruction for the disabled, and recreational horseback riding for able-bodied riders, soon became a passion. Witnessing the medical and emotional benefits derived from this unique interaction, her life and career goals were forever changed. Ultimately, her respect and appreciation for the human-animal bond compelled her to pursue a career in veterinary medicine.  

Dr. Thomas decided to return to college to pursue her doctorate in veterinary medicine, which she received from Tufts University School of Veterinary Medicine. Since graduating from Tufts, Dr. Thomas has provided quality small animal care at a variety of local veterinary practices, most recently as a relief veterinarian for multiple clinics in Massachusetts. All of her experiences have helped to shape and solidify her approach and commitment to delivering compassionate, quality care to your pets, and clear, open communication with you, our clients. She is thrilled and honored to provide veterinary medical care to dogs, cats, and horses through the opening of Veterinary Health Care of Groton.

Dr. Thomas is also a member of the Board of Directors for NEADS, National Education for Assistance Dog Services, also known as Dogs for Deaf and Disabled Americans, a member of the Board of Directors for UMass Lowell’s IACUC (a board which oversees the protection of lab animals), and she remains a licensed therapeutic riding instructor.  The Thomas family currently shares their home with two absolutely lovable rescues:

Golden Retriever

Sammy, a Golden Retriever who Dr. Thomas saved from euthanasia, and

White cat sleeping

Cali, rescued through the Lowell Humane Society after sustaining severe damage to both of her hips, who joined the household one night when she needed overnight care after her surgery. She went home with Dr. Thomas and has run the household ever since!

Micayla Hanson

Micayla was raised and resides in Tewksbury, MA. Growing up, there was always a dog and a cat in the home, building her love for animals. Micayla realized she wanted to work with animals while she was spending many weekends at dog shows and competitions with her dog niece and dog nephew. In 2009 she began her journey into the veterinary field as a receptionist in a large hospital for small animals, with the goal of becoming a veterinary technician. She worked her way to the back of the hospital as a technician's assistant in 2011. Through lots of learning, hard work, and dedication, Micayla met her goal of being a technician in 2013. She loves educating clients and has a passion for small animal dentistry.

When Micayla is not at the clinic, she enjoys spending time with her daughter Haylen and her son Zachary, as well as her fiance Walter. Micayla used to be the favorite of the family dog, Meiko, but her daughter Haylen stole his heart when she was born in 2011 and they’ve been inseparable ever since!

Meiko is a Great Pyrenees Mix who was saved from a puppy mill in Arkansas when he was 7 weeks old. He enjoys snuggling his best friend, long walks around the neighborhood, sneaking up on the couch, and digging holes under the back yard fence!


Kim Shanahan


While growing up, Kim and her family spent time helping local animal shelters and taking in pets without homes, thus sealing her love for animals and a soft spot for homeless and elderly dogs. When a pet boarding and doggy day camp facility opened up locally, she jumped at the opportunity to work there. In that time, she learned basic pet health, products, and behaviors in a quickly growing industry. After a short stint with a desk job at a computer company, she realized helping animals was where her heart was really at. Starting as a receptionist in 2012 in a large hospital for small animals, she continued to learn more regarding animal health and eventually wanted to be more hands-on and started training as a veterinary technician assistant. In 2015 she started taking online classes towards a degree as a Veterinary Technician while learning hands-on at work. After taking time to start a family, her beloved Boston Terrier, Luna, was diagnosed with a cancerous tumor. Trying to learn more in order to help ease Luna’s pain and eventually learn to walk again kick started her back into school. She is now close to finishing her degree in hopes to test for the Veterinary Technician National Exam and become a CVT, Certified Veterinary Technician. When not helping animals she enjoys spending time with her own, Charlie, a Great Dane and Louise, a Boston Terrier, as well as her husband, Keith and son, Luca.
