Dr. Brown lives on a farm in Waterford with her husband and their three young boys.  Her spare time is taken up with looking after the numerous animals on the farm, riding with her boys, fishing and watching her cowboys compete in rodeos!

Amy Martin, LVT

My family moved to a small farm in Loudoun County in 1976.  This move allowed me to own many pets, including horses.  After attending the Washington Business School in Vienna, Virginia, I worked as a medical secretary for local doctors.  My appreciation and love for animals lead me to attend the Veterinary Technician Program at NOVA Community College.  Now I am combining my medical, office background and nursing skills at Hoof & Paw.  I enjoy helping horses, dogs and cats and their owners.  Sometimes helping includes a kind word or hug; other times monitoring anesthesia.  But whatever the task, I am rewarded in the knowledge that they are receiving the best veterinary and nursing care at Hoof & Paw.
