Compassionate Veterinary Staff


Why Are We Different? We think it's three things: 

(1) Our One Team Approach.  At Vet At Your Door, our 'One Team Approach' stands out as a hallmark of exceptional pet care. This unique approach involves a dedicated team consisting of a veterinarian, veterinary nurse, and client liaison, working together seamlessly to ensure the well-being of your pet. The continuity of care, strong relationships built over time, and proactive adjustments based on deep familiarity with your pet create an unparalleled level of personalized and compassionate care. This approach extends beyond medical expertise, fostering trust and enhancing the overall pet-owner experience. With our 'One Team Approach,' you can trust that your pet receives not only the best medical attention but also the warmth and support they, and you, deserve.


(2) Everyone is less stressed. Being at home, you and and your pet are in your favorite, most comfortable place.  Additionally, your veterinary team is truly happy practicing this way.  Not only do we love the closer connections we make with you and your pets innately, but we also have a practice who prioritizes a good work-life balance.  So you can know that your veterinary team will have a relaxed, focused, motivated mindset to practice their best medicine and provide the best counsel and care for your pet's individual situation.

(3) Our focus is on you and your pet - 100%. Being in one place at one time means that we are dedicated solely to you and your pet, which makes us best able to connect with you. We can pick up on subtle signs and and go deep with difficult decisions if warranted.  We enjoy getting to know both you and your pet as individuals and the connection becomes genuine.  



Deirdre Frey VMD

Deirdre Frey, VMD


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 2015 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 and opened up a Vet At Your Door branch there as well. She lives with her husband, three children, and standard Poodle Greta.  When not working, she enjoys mountain biking, running, and chasing after her children who are chasing the dog, yes you get the idea.  Her special work interests include internal medicine, and particularly geriatric feline medicine.

Abigail Messina DVM

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.  For 7 years she worked in a very busy brick and mortar practice in North Dartmouth, MA 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 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.

Julie Greenlaw BVMS

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.

Jesse Robinson DVM

Jesse Robinson, VMD




Dr. Jesse Robinson earned a bachelor's degree in Computer Science from the University of Virginia in 2003, but he soon realized that the tech industry was not where his heart lay. He moved to Portland, ME after graduation and eventually found a passion for working with animals. He started taking required courses at USM and in 2014 he graduated from the University of Pennsylvania School of Veterinary Medicine. Dr. Robinson began his veterinary career doing a mix of large and small animal medicine in Pennsylvania.  In 2021, he had the opportunity to move back to southern Maine to work at the Animal Refuge League of Greater Portland. After 2 years working in shelter medicine, Dr. Robinson found that he missed the personal connection of working directly with clients and their animals and decided to go back into general practice.


Dr. Robinson believes that in-home care is a great option to reduce stress for animals and their owners;  he also cares deeply about helping owners and their pets navigate the challenges of end of life care and understands how important it is to be able to do this in the comfort of a pet’s own home.


Dr. Robinson lives in Scarborough with his wife and fellow veterinarian Megan, their daughter Dagny, 4 dogs (Cosby, Poppyseed, Bagel and Egg) and 3 cats (Spike, Ooly and Fig Newton).
