Mary Romine, LVT
Mary joined the Colony team in October of 2022, but she has been working in the veterinary industry for 20 years! She started as a tech in a 24-hour hospital and moved through a couple of different hospitals and clinics. Mary ended up at another 24-hour hospital and was promoted to Technician Supervisor and after a few years was promoted to Practice Manager. She moved from Texas to Virginia in October 2022 with her husband and pets. Mary grew up on a dairy farm in Vermont and knew from a very young age that she would have a career working with animals. She loves talking to clients about their pet's health and what they can do to help their pet live as long and as happily as possible. Outside of the hospital, she enjoys the outdoors, hiking, walks, the beach, gardening, and spending time with her own pets. Mary has 11 pets total - 5 dogs, 2 cats, and 4 rats!

Eva Prenger, LVT
Eva has been working in the veterinary field since 2012. She started as an assistant at a combined general practice and ER in Milwaukee and then worked at a small animal and exotics practice and achieved her license as a Certified Veterinary Technician. Eva then moved to Virginia in 2023 and joined the Colony team as a Licensed Veterinary Technician in 2024. She loves helping pets and their families every day, but especially through the sometimes unexpected and difficult times where they need a little more empathy and care.
Outside of work, she enjoys hiking, kayaking, crocheting, hand embroidery, and family activities with her husband and two kids. Eva has two dogs, a chihuahua and a supermutt, a cat, and a fish tank!

Ardra Decker, Receptionist
Ardra joined the Colony Animal Hospital team in July 2018, bringing with her years of experience and a deep love for animals. She’s been in the veterinary field since 2013, starting out as a kennel assistant before transitioning to the front desk in 2022, where she now welcomes clients with a smile and helps keep things running smoothly.
For Ardra, the best part of working in veterinary medicine is being a voice for animals and watching them heal and grow. Her compassion and dedication shine through in every interaction.
Outside of work, Ardra enjoys spending time with her husband and parents, exploring new places, and diving into all kinds of curiosities—she’s an avid collector of oddities and antiques. At home, she shares her life with three cats—Batty, Binx, and Flynn (a spirited orange-and-white tripod)—and two dogs, Marley the chihuahua mix and Zeke the shih tzu.
