Bev Hollis, DVM
Dr. Hollis moved to the northern Virginia/ Maryland region in 2006 from Nashville, where she had lived for 13 years. She earned her 
undergraduate degrees in English, Math and Biology from the University of Minnesota and George Mason University and graduated Magna Cum Laude from the University of Tennessee College of Veterinary Medicine in 1997.
During her years in Nashville she worked in a small animal practice, started her own veterinary housecall practice, and became Nashville’s first full-time shelter veterinarian. She is an avid supporter of greyhound rescue and was a co-founder of Operation Scooby, a non-profit organization that sent teams to Spain annually to work as volunteers at the largest “Galgo” (Spanish greyhound) shelter there.
She became D.A.R.T (Disaster Animal Response Team) certified in 2001. This certification came in handy when she had the opportunity to lead a team of 10 volunteers to New Orleans in 2005, 5 days after Hurricane Katrina had struck the region. Her team spent 14 days deep in the 9th ward and to this day those rescue efforts remain Dr. Hollis’ most rewarding contribution to animal care.
Dr. Hollis believes strongly in the extremely important role animals play in people’s lives and approaches each veterinary case with a deep respect for this bond.
She lives with her 13-year-old shelter dog, Lily and the memory of her beloved PBGV, Niles – the world’s funniest dog.
In her spare time she is an avid photographer – both film and digital. She loves adventure travel, anything Apple (Mac, not the fruit), running, yoga and golf.
