Meet Our Doctors

Dr. Michelle L Thomas, D.V.M

Dr. Thomas was born and raised in the Pacific Northwest. Her passion for animals led to a Bachelor of Science degree in Zoology at Washington State University in 1992 followed by a Doctorate of Veterinary Medicine, also at WSU. After graduating with high honors in 1996, she moved to Fort Collins and began working at Mulnix Animal Clinic. She feels very privileged to have had Dr. Mulnix as her mentor, friend and colleague for so many years. She purchased Mulnix Animal Clinic in 2015 and values the compassionate, talented and loyal Mulnix Animal Clinic team and wonderful clientele.

Dr. Thomas continually strives to improve her knowledge and stay on the leading edge to provide you with the latest treatment options. Her ultimate goal is to help educate and guide you through individualized treatment plans that will provide your pet a long, healthy and happy life at whatever life stage they may be in. She has also established a network of trustworthy specialists to consult or refer to when necessary. Her family oriented approach and enthusiastic demeanor is welcoming to everyone. She looks forward to challenging cases and meeting new and old loyal clients every day. Dr. Thomas is a proud member of the American Animal Hospital Association, American Veterinary Medical Association and the Larimer County Veterinary Medical Association.

When away from the clinic, she enjoys time with her family and all of their sporting events. Her daughter, Shelby, is in high school and softball is her passion. Her son, Garet, is in middle school and loves football and baseball. Her husband and high school sweetheart, Mike, has become an avid animal lover too. Her kids enjoy pet sitting and that has taught them responsibility, respect and appreciation of the love and companionship pets offer. When not at a kid sporting event she can be found walking the dogs, snow skiing, playing indoor soccer, reading or with friends.

Her furry family currently consists of “Bean” a rambunctious and snuggly adolescent golden retriever that is still trying to master the art of “retrieving”, “Bee” a mellow, rescued 5 year old golden retriever from Wyoming that loves everyone and everything, and 2 shelter kitties: “Duffy” aka ‘Duffer Fluffers’ a grey tabby and “Twix” the 16 pound ‘kitten’ that she and her kids came home with from the shelter. They also have various fish. 

Dr. Kelly Gaffney, D.V.M

Dr. Gaffney is passionate in her work with animals, both big and small. She has been a warm presence of the Mulnix team since 2015. Dr. Gaffney graduated from Colorado State University in 2013. She currently practices both equine veterinary medicine and small companion animals. Dr. Gaffney believes strongly in preventive medicine, educating her clients on the best care for their pets, and building a strong foundation between herself and her clients.

Dr. Gaffney always stays current on the latest treatment and medication options available in veterinary medicine.  She believes that the best standard of care can only be given if we are constantly exploring what new strategies are out there to diagnose and treat our patients. She strives to be compassionate towards fearful pets. She believes a stress-free environment is essential for patients and has many strategies to help anxious furry ones. She considers the Doctor patient relationship a collaborative effort and can tailor treatment plans to suite both client goals and expectations as well as what is in the best interest of the pet.  She takes time to answer questions and explain case details about your pet so that hopefully an understanding of what is going on and what options are available are clear so that confidence can be gained and ultimately pets succeed.

Since childhood Dr. Gaffney’s passion has been her love for horses. She currently enjoys riding and caring for her own horses; Slew her retired thoroughbred and Abraham her welsh pony. Helping her keep everyone in line are her pack of cattle dog pups. Adelaide, her youngest craziest baby is a bit of a cartoon in motion, hilarious, busy, and somewhat of a clown. Delilah is a little more introverted and challenging, but keeps things interesting with her unique personality. Finally, Gunny, the dopey and fun-loving Labrador Retriever.

Dr. Gaffney loves to paint and draw using many mediums, and creates mosaics, pottery, and works with stained glass. Moving from South Carolina to Colorado in 2000, Dr. Gaffney loves to get back to the ocean when possible, drink sweat tea, and visit her family.

Dr. Sarah Mc-Palmer, D.V.M, MBA

Dr. Sarah Mc-Palmer is a Colorado native born and raised in Golden where she grew up skiing, hiking, and enjoying the foothills of the Rocky Mountains. Her passion for science and medicine led her to University of Colorado at Boulder for dual undergraduate degrees in Molecular Biology and Integrative Physiology. Dr. Mc-Palmer always wanted to be a veterinarian since she was very little and eventually moved to Fort Collins to pursue her Doctor of Veterinary Medicine at Colorado State University alongside a Masters in Business Administration. 

Sarah is passionate about her patients and providing the best care possible to each and every cat and dog who walks through the door, tailoring each experience to theirs and their owner’s needs. She strives to provide both excellent patient care and client care and education on the most up to date treatment options. She is excited to be a part of the Mulnix team as they have a tried and true reputation in the Fort Collins area for providing the highest quality care, having very friendly  and accommodating staff, as well as a kind culture for her to grow and learn as a veterinarian. She has a special interest in general practice as it allows long-standing relationships with clients where she gets to see families and their pets grow throughout the lifetime of visits. She is also interested in the operational and financial aspect of veterinary medicine and works as a market consultant for Blue Heron consulting part-time to help veterinary hospital owners and veterinary-related business owners realize their dreams of running successful, healthy practices.

In her spare time, Dr. Mc-Palmer can be found in the mountains and canyons surrounding Fort Collins skiing, rock climbing, and adventuring with her husband Eric and dogs. She has two husky mixes, Marlon Brandog (husky/lab) and Penguin (husky/border collie), who keep her busy, well-exercised, and make life a lot funnier on the daily. When she isn’t outside enjoying the beauty of Colorado, she is likely to be taking a yoga class or hanging out on her patio with her plants or grabbing a good bite to eat in Old Town.

Official Clinic Greeter/Supervisor

Thomas came to Mulnix Animal Clinic in 2009. Tom loves to spend his days whimsically hanging out at the front reception desk greeting anyone who will give him some cookies. He loves looking down on his canine counterparts from his bed and casually brushing off their attempt to get his attention. Often supervising any care given to his feline cohorts to ensure that they are getting the best care possible. Keeping a supervising eye on all staff members to make certain they feed him at appropriate times (all the time in his mind), or else keeping a strict discipline protocol of breaking into client food bags! Tom is wonderful part of our staff and we all love having him as part of our team.
