Arlee Barnes

Office Administrator

Arlee is a Lancaster, PA native who grew up with a true appreciation of the outdoors, nature and animals. The youngest of four, she had a competitive drive, especially when it came to sports. Her childhood nickname was "Fragile," often finding herself sidelined or playing through the pain of orthopedic injuries. After a shoulder surgery at age 13, her years-long journey into the PT realm started.

After graduating magna cum laude and working as an Expanded Functions Dental Auxiliary, Arlee took a chance and moved to Virginia in 2014 on a whim to see what else life had to offer. She started work in the beauty industry, walking dogs on the side. In 2015 she started her own dog walking and pet boarding business in Ballston. This is how Arlee met Abigail ‘Pancake’ Stack and her human, Mary Jean!

Fast forward a few years and Arlee became a patient at GFPT after Mary Jean’s parents' uncoordinated yellow lab puppy, Zoe, took a nosedive into Arlee’s newly un-booted ankle. After being broken and bruised, Arlee became a true believer in the healing art that an exceptional physical therapist can offer.

When not at the office, Arlee spends time with her rescue dog, Gidget. When not tending to dogs, Arlee enjoys having bonfires, driving manual transmission, eating oysters, drawing, exploring the beauty that is life and actively avoiding social media.
