Margeo Houston

Mona Sawaya

Mona joined our practice in March 2023 and is the last smiling face you’ll see as you leave our office. She works at our checkout desk, helping schedule follow-up appointments and answering any final questions. With her bright personality and signature reader glasses, she brings a fun, welcoming energy to the front office.

Tracy Campbell

Tracy joined our practice in January 2023 and serves as Dr. Shaw’s surgery coordinator. She works behind the scenes to secure insurance approvals and coordinate surgical care, helping guide patients through each step of the process. When she’s not at work, you may find her doting over her Shih Tzu puppies.

"Our patients always come first, and we truly love what we do. We also believe that caring for one another—and sharing a little laughter along the way—makes us better at caring for you."
In loving memory of our Practice Manager:
Joann Rock
