Dr. Vera Calpeno


Owner, DVM

Before her medical career, Dr. Vera (as she prefers to be called) served in the U.S. Navy, acted as an administrator, and was a Delta Air Lines flight attendant. After the devastating events of 9/11, Dr. Vera left the airline industry to rekindle her childhood dream of becoming a veterinarian, working as a Middle Eastern dance teacher to support her studies.

Upon receiving her DVM degree from the University of Georgia in 2009, Dr. Vera began practicing in the Annapolis area, which brought her closer to family and friends. She worked as an associate veterinarian for four years at Greater South River Animal Hospital (formerly Reichart Animal Hospital) in Edgewater, and at Chesapeake Animal Clinic in Owings, Maryland.

While planning to establish her own practice, Dr. Vera worked as a relief veterinarian for Anne Arundel, Calvert, and Howard County area clinics, and practiced emergency medicine at AVPES in Calvert County. Her search for a vibrant and client-convenient location led to the busy Pasadena crossroads, now the home of Happy Tails.
