Meet the RxSmile Orthodontic Staff

Lisa – Practice Administrator

Hello! My name is Lisa and I am the Practice Administrator here at RxSmile. I have been with Dr. Greenberg and RxSmile from his opening day in 1988! My job is to oversee the day-to-day functions of the office. I enjoy visiting with the parents and patients at their visits and getting to know more about each individual.

I have two wonderful adult children. In my spare time I enjoy thrift shopping, and spending time with my family and friends.


Gayla – Treatment Coordinator

Hi! My name is Gayla. I am Dr. Greenberg’s treatment coordinator at RxSmile. I have been in orthodontics for over 18 years and have worked at RxSmile since 2001. I began as a technician working with patients in treatment and moved to my present position as treatment coordinator over six years ago. I enjoy meeting new people and seeing the patients become more and more confident and happy as their smiles change! We have a lot of fun while delivering excellent results!

In my spare time, I love to hunt, camp, sing, and spend time with my grandbabies!
