Peggy Breckenridge, MS, MBA
Practice Manager

Peggy began at MEAC in 1995 as a technician.  She was promoted to Business Manager in 2004 and had her title changed to Practice Manager in 2008.  She received her MS in Cybersecurity in 2013 and her MBA in 2014 from UMUC.  She resides in Germantown, MD with her 8 dogs, Zipper, Snap, Bows, Ribbons, Buckles, Bobby Pin, Rose Marie, and Daisy Mae all of which were adopted though the clinic due to health issues.  She also has one cat, Livingstone who she hand raised as a baby and five turtles Teddy, Spike, Sunny, Burtle, and Shemus.  She originally entered into Veterinary Medicine due to a long time desire to go to vet school but decided that she preferred the business side over the medicine.  Her favorite part of her job is being able to support the medical staff in their efforts to diagnose and treat the many patients that come into the clinic.  Nothing thrills her more than a seeing a happy reunion between a pet and their parent(s) after a stay at the clinic.
