Deirdre Frey, VMD

Dr. Frey and one of her patients, the beautiful troublemaker, Nellie jane.

Dr. Frey earned a BS in Operations Research and Industrial Engineering from Cornell University in 1999.  After working for a few years as a computer programmer, she decided to fulfill her life-long dream of becoming a veterinarian.  She obtained her doctorate in veterinary medicine from University of Pennsylvania in 2008 and completed an internship at the New England Animal Medical Center in West Bridgewater, MA.  In 2011, she achieved her other life-long dream of living in Maine.

After working at traditional brick-and-mortar veterinary practices, she witnessed first-hand how stressed animals can be at the veterinary office.  She started Vet At Your Door, P.C. in order to be able to connect on a less stressful and therefore deeper level with her patients and their parents.  She enjoys getting to know each animal and working with their dedicated owners to maximize their quality of life, minimize pain, and keep them healthy for as long as possible.  And when it becomes an animal's time to leave this earth, she feels it is a gift to be able to help both the owner and pet through this difficult, yet peaceful and oftentimes beautiful process.  

Dr. Frey moved from Durham, Maine to Carrabassett Valley, Maine in 2017 with her husband, three children, German Shorthaired Pointer Ruby, and fraidy cat Joey.  She is looking forward to expanding Vet At Your Door's service area and bringing the benefits of at-home veterinary care to Maine's High Peaks Region. When not working, she enjoys mountain biking, running, and chasing after her children who are chasing the dog who is chasing the cat, yes you get the idea.  Her special work interests include internal medicine, and particularly geriatric feline medicine. 

Abigail Messina, DVM

Dr.  Messina had dreamed of being a veterinarian since she was 7 years old.  After she earned a BS in Biology from Mount Holyoke College in 2005, she went on to fulfill that dream and graduated from Mississippi State University - College of Veterinary Medicine in 2009.  She worked in a very busy brick and mortar practice in North Dartmouth, MA for the past 7 years where she developed a love for acupuncture, behavioral medicine, and hospice care; however, she always knew she wanted to live and work in Maine.  Finally, after years of waiting, she and her family made the move in 2016.

Dr.  Messina is extremely excited to join Vet At Your Door, and believes wholeheartedly in the benefits of lower stress home visits for routine vaccines, euthanasia, and everything in between.  She has a strong passion for geriatric and hospice care, and believes that being able to offer compassionate care for both owner and pet in the difficult times of illness and end of life is the most rewarding part of veterinary medicine.  She also loves practicing the art of acupuncture, and is continuously amazed at the wonderful benefits this can bring to many different cases. 

Dr.  Messina lives with her husband - Scott, twin sons - Finnegan and Oliver, Great Dane - Pickles, Shepherd Mix - Brewster, and crazy cat - Squid in Brunswick.  Outside of work she enjoys hiking, camping, swimming, playing the piano, and spending quality time with her family.

Dana Peirce, DVM


Dr. Peirce earned a Bachelor of Science degree in Biology as a Morehead Scholar at the University of North Carolina at Chapel Hill in 2001. While she spent the next few years training and competing as a member of the National Rowing Team, she was always thinking about what her next step in life would be.  The practice of medicine had attracted her interest for many years, but it was the adoption of the little bulldog named Jasmine that set her on a course toward pursuing veterinary medicine. Dr. Peirce earned her doctoral degree at Cornell University College of Veterinary Medicine in 2013, and completed a post-graduate internship in small animal medicine and surgery at The Animal Medical Center in New York City. After graduation she joined a wonderful conventional practice in Manhattan, but the completion of her husband’s medical training led to a move to Maine—and she is so happy it did!

Having provided occasional at-home care to patients as needed over the years, Dr. Peirce is thrilled to be joining Vet At Your Door to provide this valuable service to all of her clients and patients. Dr. Peirce lives in Cumberland Foreside with her husband Jon, daughter Hartley, tiny old schnauzer Mina, and a small flock of hens. In her spare time, she enjoys reading, hiking, spending time with family and friends, and, after years of city living, gardening--though a Hubbard squash just took over her first attempt at a vegetable garden!

Heather Crispell, DVM


Dr. Crispell earned a Bachelor of Science degree in Biology at Saint Michael’s College in 2006. She spent the next 3 years in biomedical research in both Downeast Maine and in Fairbanks, Alaska. She had always loved veterinary medicine and in 2013 she graduated from Cummings School of Veterinary Medicine at Tufts University. After graduation she worked at traditional brick and mortar veterinary practices in both Maine and Massachusetts. While working at a busy practice in West Gardiner, she developed her love of (then rare) house calls.

Dr. Crispell is very excited to be a part of Vet At Your Door to be able to provide high quality, low stress veterinary visits to all her patients and clients. Dr. Crispell loves providing individualized care to each of her patients to provide the best quality of life. She finds geriatric medicine and hospice care as some of the most rewarding aspects of veterinary medicine. She enjoys providing compassionate care at all stages of life, from puppies and kittens to making sure that senior pets as comfortable as possible. 

Dr. Crispell lives with her husband Eli in Durham with their wild and crazy cat Baxter. She loves being outside exploring.  From skiing and skijoring to kayaking and stand-up-paddle boarding, she enjoys getting outside year round.  When she isn’t off on an adventure you can find her gardening and spending time with family and friends.

Julie Greenlaw, BVMS


Dr Julie Greenlaw was born in Maine and has lived here most of her life. She was lucky enough to have a dear friend and mentor who inspired her to become a veterinarian. It took her a while, but after raising a family she finally got up the courage to go after her dreams, and with the support of her family she pursued veterinary school. She received her undergraduate degree from the University of Maine at Orono and moved to Scotland where she pursued her veterinary degree and graduated from the University of Edinburgh. She has mostly worked as a mixed animal practitioner working with both small and large animals. She owned and operated her own mobile veterinary practice on the coast of Maine, which was primarily for farm animals and horses, where she specialized in small ruminants, but also provided at-home euthanasia for family pets.

Five years ago, her husband’s job took her to Florida where she worked for an at-home hospice and euthanasia veterinary practice. While the job was rewarding in many ways, living in South Florida was not a good fit for her. She has returned to the state she loves and is now living near her family. She has always lived near the coast, but is truly enjoying the mountain life. Dr Greenlaw prefers to see patients in their own home and environment. She feels she gets a better snapshot of each pet’s health and living situation so she can better help them stay healthy. She especially enjoys meeting the local families and their much-loved pets and farm animals.

On her days off she spends time with her grown children and her two grandchildren that have been growing up in Carrabassett Valley. Dr Greenlaw and her husband especially love ocean kayaking off the coast of Maine. They also spend time hiking, biking and travelling. She is truly happy and excited to be working for Vet At Your Door and serving the people and pets of Maine in their homes.
