Dr. Kristen Hitt

DVM, Owner

Dr. Kristen Hitt has been practicing Veterinary Medicine in the northern Virginia area for several years. Prior to attending vet school, Dr. Hitt was a registered nurse at a local hospital. Using her nursing skills while caring for a stray dog injured by a car, she realized that her dream job would be to combine her long love of animals with medicine. With the love and support of her family, Kris went to school at Virginia-Maryland Regional College of Veterinary Medicine and earned her Doctorate of Veterinary Medicine and she became “Dr. Hitt”. As a student, Dr. Hitt was awarded the American Animal Hospital Association’s Student Achievement Award for outstanding achievement in Small Animal Medicine. After graduation, Dr. Hitt worked at a practice in Falls Church and did relief veterinary work for hospitals in Centreville, Chantilly, Clifton, Upper Marlboro and Germantown as she worked toward her goal of opening her own dream hospital, Mainstay Veterinary Practice.

Dr. Hitt has a strong interest in surgery and has completed multiple continuing education courses in ultrasound. She also believes in ‘giving back’ and started a feral cat program in Falls Church. She has traveled to Kentucky, and most recently to North Carolina, to perform surgeries on rescued puppy mill dogs and animals from low socio-economic areas and she has donated her time to the Animal Welfare League of Arlington.

While not busy helping animals, Dr. Hitt enjoys spending time with her husband and their dogs, Dibs and Moxie, her ‘mutt’ herd of horses at their family farm. Of course, she also enjoys any time she has with her four children, but that time is dwindling as her nest is officially empty. In addition to vet medicine, Dr. Hitt loves traveling, scrapbooking, organizing, and diet coke. She resides in Fairfax with her husband and dogs.

What is the Most Rewarding Part of Your Job?

Helping my clients strengthen their bonds with their beloved pets who are family members and ensuring that they have the best quality of life possible

What is the Hardest Part of Your Job?

When financial constraints limit successful (or possibly successful) medical care

What is One Medical Case that you Remember like it was Yesterday?

I remember removing a bleeding liver lobe in a small dog that would have died when the owner could not afford the specialist. The cancer was contained in the one lobe and the dog lived several more years!

What's your Favorite Activity Outside of Work?

Walking with my dogs at my farm on the weekends

If you could spend a day with any famous person in the world, dead or alive, who would you choose and why?*

Can I say....Jamie Fraser? LOL

Tell me about the moment you chose to become a doctor.

Animals have always been a part of my life, but I didn't consider being a vet until I was a registered nurse at a hospital. I considered going to medical school and considered the nurse practitioner route, but I had some reservations. One weekend, a stray dog was hit by a car near our farm. I rushed him to the vet for emergency surgery. I had mentioned to the vet that I was a nurse and she said, ``Great, you can help!`` I monitored anesthesia and she did the surgery to save the little dog. At that exact moment, I knew that becoming a vet would combine my love of medicine with my love of animals. My husband encouraged me to apply to vet school and I have never looked back. I was the only married vet student with children and could never have succeeded without the support of my family. It took a village and I love my job every day!

If you could only pick TWO types of cases in veterinary medicine to work on for the rest of your life, what would they be?

Dr. Caroline Chamarande


Dr. Chamarande (Dr. C) was born and raised in Fontainebleau, France. After she received her French baccalaureate, she earned her Bachelor of Science and her Masters degree in Chemistry from American University. She worked for the chemistry department at the Naval Research Laboratory in DC, but abandoned her career as a chemist to follow her lifelong dream of becoming a veterinarian. She graduated Cum Laude from the Virginia-Maryland Regional College of Veterinary Medicine (VT). After 24 years of service at a practice in Falls Church, Dr. C. decided that it was time for a change. She joined MVP where the owner and staff share her values in providing quality veterinary care and believe in strengthening the bonds between pets and their families to assure a long and happy relationship. She enjoys the atmosphere at Mainstay for it allows time to get to know the pets and their owners, educate owners on veterinary care, discuss training, play with puppies and kitten, and just plain socializing pets!

Dr. C has an active interest in Internal medicine and Animal Behavior and Training. She is a longtime member of AAHA, VVMA, NVVMA, and D.C. Academy of Veterinary Medicine. Dr. Chamarande is federally accredited by the U.S. Department of Agriculture, which authorizes her to perform evaluations and issue International Health Certificates for pet travel.

In her free time, Dr. C enjoys time with her husband, three children, and her furry pets. She has a frequently-rotating “pet population” at her house as she often finds herself taking in animals that need new homes. Currently the pet population at Dr. C’s household consists of Lazarus (a rescued Yorkie), Chewy (a rescued Anatolian Shepherd) and Rosie (a re-homed chihuahua). That is about all the animals her poor allergic husband can tolerate at this time.

It was her beloved family dog, Cooper, that inspired her start in veterinary medicine back in 2016. In his last year and a half of life, he taught her more than a few things about senior dog care and the dedication it takes to manage a chronically ill pet-through medications, laser therapy, acupuncture, and hydrotherapy – he was a perfect patient!

Practice Mascots

Emmy, R.I.P

Emmy was Dr. Hitt's 13-year-old French Bulldog that passed away peacefully in 2020 after being diagnosed with a very large brain tumor. She was a part of Mainstay Veterinary Practice since it's very beginning, accompanying Dr. Hitt to the construction site and then to work in the office once the practice opened. Emmy was famous among the original MVP clients. She enjoyed nestling in her bed as well as sleeping on her heating pad. Emmy grew up with a chocolate lab brother, Dibs, and a shepherd mix sister, Moxie. Emmy could frequently be found stealing the other dogs' beds. While not sunbathing, she could easily be located by listening for her unique snorting noises. Frequently breaking the rules, Emmy became an angel at the sight of Twizzlers. She loved little kids that were ``her size`` although deep down Emmy thought that she was a giant dog. She wasn't even afraid to greet horses! Her big personality made up for her small size.


Laz, also known as jumping bean, was turned over to Dr. C when a couple opted to euthanize him at only a couple weeks old as he was comatose from Parvo. Asking if she could try to save him, Dr. C spent days nursing him around the clock until he finally pulled through! You would never know his rough start to life by his cheerful attitude, happy demeanor and wiggling body. Laz loves all dogs and people and is a little energizer bunny. He runs frantically around the practice with his own jumping-like gait and all you see is flowing hair darting by! We appreciate the extra “mopping” he does for us as he covers a lot of ground quickly!


Reese is Brittany’s 5 year-old Pekingese/Basset Hound mix. She basically looks like a Pekingese head attached to a miniature Basset-shaped body. She has a silly personality to go with her silly shape. Reese loves running sprints up and down the practice hallway and wrestling with her best friend, Laz. Reese is a ham when it comes to wanting attention and will try to be as cute as possible so someone will come say “Hello”. Her go to position is usually on her back so she can get a belly rub. Reese puts a smile on everybody’s face and is a dog who can cheer you up when you’re having a bad day.


Veterinary Assistant

Roo is Brittany’s Husky mix. She has the voice and mannerisms of a husky and the hunting instinct of a hound. She is always on squirrel patrol, but we think she really just wants to be friends with them. Being part husky, she always has a lot to say. She is very talkative and can be demanding when she wants something. She loves to give handshakes and high fives. Roo is Reese’s younger sister and they are best friends. You can often find them playing tug of war, cuddling or grooming each other. She always keeps us laughing. She loves to run and play but is also happy to cuddle on the bed at night. There is never a dull moment when Roo is around. She keeps life entertaining.


Mato is Blaine’s 3 year-old chocolate lab. His name means little bear in Sioux. He can frequently be found around the practice, but especially on the scale staring down the receptionist asking for more treats. When not begging for food, Mato can be found on-hold with the ASPCA animal poison hotline as he likes to eat things out of spite when his parent’s aren’t giving him adequate attention (by Mato standards). The list of items ingested include glass bulb ornaments, pepper spray and 25 citronella tea candles. Mato enjoys his farm, swimming and hanging out at Grandma daycare with his best bud, Dibs, also a chocolate lab.
