I also treat gastroesophageal reflux and reflux-related esophagitis, offering tailored solutions that significantly enhance my patients' quality of life.

Patients often highlight my professionalism, empathy, and dedication to understanding their unique needs. I take the time to listen and fully grasp their goals because I believe every case deserves a personalized approach and a clear path toward success.
