Modern Medicine. Traditional values.

Our Veterinarians

Amy H. Hollengreen, VMD

Dr. Hollengreen was raised in northern Virginia and began working with animals when she was a young girl. Her parents raised champion hounds, including Rhodesian Ridgebacks, Harriers, Black and Tan Coonhounds, and English Foxhounds. Their kennel, Qa'Taba Kennel, was moved to southern Pennsylvania in the mid-1980s and grew to house over 100 dogs.

Dr. Hollengreen graduated from Boston University with a BA in Biology. She received her veterinary degree, Veterinariae Medicinae Doctoris (VMD), from the University of Pennsylvania in 1993. Upon graduation, she moved to Nashua, New Hampshire, and began working as an associate veterinarian at Amherst Animal Hospital. Dr. Hollengreen purchased the Amherst Animal Hospital in 2000 and became the sole owner in 2006.

As a general practitioner, Dr. Hollengreen sees outpatient appointments, manages hospitalized pets, and provides surgical and dental services. She performs a wide range of surgeries including routine spays and neuters on dogs, cats, and small mammal exotics, abdominal surgery, ophthalmic and cosmetic surgeries, and oncologic surgeries. Her medical interests include management of chronic renal failure, hyperthyroidism, and other endocrine diseases, pediatric medicine and infectious and parasitic diseases. She also provides comprehensive medical and surgical care for cats within the Kitty Angels rescue organization.

Dr. Hollengreen and her husband, Christopher Knoell, Ph.D., moved to Milford in 1995. Together with their two daughters, they share their home with three cats, Bingo, Willa, and Mari.


Meaghan Hanlon, DVM

Dr. Hanlon was raised nearby in Derry, NH for most of her life. She traveled south for four years for her undergraduate degree at Clemson University in order to be close to her grandparents, pursuing a B.S. in Biochemistry and a minor in Animal Science. Following graduation, she moved back up north to complete her Doctor of Veterinary Medicine degree at Tufts University.

Dr. Hanlon is a huge fan of all of her patients – cat or dog, big or little. Some of her biggest interests lie in preventative medicine, internal medicine, diabetic and

hyperthyroid management, diagnostic imaging, and more. When she’s not working, her time is best spent with her family, friends and two kitties Koda and Wilson, and some painting, writing, or hiking.
