Moira Nusbaum (Myers), DVM/Owner

Dr. Nusbaum was born and raised in Gapland, MD a small rural community in Washington County. Growing up, she competed successfully in the Hunters all the way through Amatuer/Owners. A love of horses was instilled in her early, and followed her through high school and college. After graduating from West Chester University in PA, she worked for a year as a nurse at the Marion duPont Scott Equine Medical Center in Leesburg VA. The valuable experience solidified the goal of becoming an equine veterinarian. Moira attended the VA-MD Regional College of veterinary medicine, graduating in May 2010. Soon after graduating, Moira accepted a position at the Piedmont Equine Practice, in The Plains, VA - an area known for its dense population of sport horses. Despite being offered an opportunity to stay on at Piedmont long term, Moira decided to follow her heart and move home to start her own practice. She founded PenMar Equine in June 2011 and has enjoyed all aspects of practice ownership since. Moira married her high school sweetheart Stinson in 2009 and together they welcomed Colten in 2014. In her spare time (funny!) Moira does ride her horse 'Three' mostly on the trails.

Dr. Annie Chavent was born and raised in Richmond, Virginia. She first discovered her love of horses at a birthday party as a 6-year-old and has been riding ever since. She competed locally in hunter/jumpers and horse trials through high school and rode on the IHSA team in college. She graduated Magna Cum Laude from Princeton University with a Bachelor’s degree in Ecology and Evolutionary Biology and went on to complete veterinary school with honors at North Carolina State University in Raleigh. During veterinary school, she was active in the student equine club, student government, and the veterinary business management club. Following graduation, she completed an intensive, equine-focused internship at the Piedmont Equine Practice, the same practice that Dr. Moira interned with a few years prior.

Dr. Chavent is excited to join the PenMar Equine team! Her current professional interests include diagnostic imaging, podiatry, and internal medicine. In her free time, Dr. Chavent loves to run, catch up with friends, and make puns in everyday conversation. She looks forward to meeting you and your four-legged family
