Dr. Hannah Smith
Dr. Hannah Smith is excited to join the MCV staff in June 2017. Prior to joining MCV, she worked as a mixed animal veterinarian in Lancaster, Pennsylvania. Dr. Smith received a Bachelor of Science degree in Dairy Science from Virginia Tech in 2010 and her DVM degree from the Virginia-Maryland College of Veterinary Medicine in 2014. She is originally from Clear Spring, Maryland, and was a client of Dr. Horst’s when she was younger. Dr. Smith is excited to return to the area and continue her veterinary career.

In her free time, Dr. Smith enjoys showing and working with her dairy cows, cheering on the Hokies, Redskins, Nationals, and Capitals and, in the summer months, spending as much time outside as possible. Dr. Smith lives in Hagerstown, Maryland, with her dogs Cammie (a German Shorthaired Pointer), and Nala (Golden Retriever x Poodle).
