    She compared my current endoscopy results to those reported by a NYC doctor and said I do not have Barrett's Esophagus which was reported by the NY doctor. She explained probably why the other doctor's report was different. Certainly it is important to know I don't have that disorder nor metaplasia which was reported. The disorder required a certain diet too. Excellent doctor.

    This was my very first visit with Dr. Nath. So while she didn't have any of my medical history at the start of our visit, she took a very thorough history from me and spent ample time learning my history to understand why I was establishing care. I told her I had never felt so heard and seen by a doctor, because she spent so much time with me, wanting to help dig into what could be causing my symptoms, and try to make sure we weren't recreating any previous attempts to address the symptoms. She was more thorough than any doctor I have ever seen, and I am very excited to continue working with her to hopefully finally find relief for my issues.

  • Reviewed on 10/28/2025

    Dr. Nath listened to me and took my concerns and updates seriously. She was never dismissive of anything I had to say. She gave me all the time I needed, which was greatly appreciated. I wasn't able to book an appointment in the timeframe she requested because there were no open spots in her schedule, even for my virtual appointment. MGB could do better by not overfilling provider's caseloads and putting a hold on new patients until that provider meets a certain threshold of open appointments per week/month. MGB could hire more providers in order to accommodate new patients and get them seen in a timely manner. Current patients should not have to wait extended times between appointments, beyond what a provider requests. New patients should be able to see a provider in a timely manner as well. You can do better MGB, you are one of the top healthcare providers in the country and in the world. Your patients deserve the most innovative & comprehensive care; that includes their healthcare coordination.
