Maureen Walls, RN: Patient Coordinator

Maureen Walls, RN, our Patient Coordinator at Boston Plastic Surgery, says that the reason she believes the staff is so extraordinary is that Dr. Samaha has chosen each one for not just their professional expertise but, just as importantly, the way that they treat patients. From the friendly, helpful attitude at the front desk as soon as you walk in the door to sensitive post-surgery care, everyone on the team treats each patient like they are a part of the family. The staff is made up of mature, seasoned professionals with extensive experience in the field of cosmetic surgery.

“Change is never easy and can be scary. We really understand that, especially when it’s in such an unfamiliar terrain like cosmetic surgery. Our job is to make each patient feel informed, comfortable, and cared for. The experience should be as satisfying as the results.”

Maureen combines her extensive experience as a nurse with a genuine caring for people to help provide a safe and comfortable experience for all of our patients.
