Veterinary Assistant

Maddie was born and raised in Northern Virginia and has been in the veterinary field since 2016 when she started work at the front desk in general practice. 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!

Maddie enjoys spending time with her family and navigating the ups and downs of training their sweet and stubborn new rescue puppy named Ellie. Outside of work, she enjoys watching a good documentary, catching a local theatre production, gardening, and if it’s a race weekend- watching a Formula One race.

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. When 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.
