Karla Maradiaga, RDA

"I am originally from Guatemala. I started working in the dental field in 2013 as a general assistant. I enjoyed  dentistry and working with patients so much that I became a Registered Dental Assistant, from Northern Virginia Community College.

My priorities are to always make patients feel welcome and make them feel comfortable. In my spare time, I love spending time with my husband and three beautiful children, and our big and lovely dog (Rocky). As a family we enjoy camping, going to the beach and playing with Rocky. I look forward to seeing you at your next visit to provide all the best care we provide at American Dental."
