Dr. Brenner has always been great and when my wife had some concerns regarding her breathing, I told Dr. Brenner and he asked me to bring her in with me on my next appointment and he saw her right away.

As is the hallmark of HMH, he works in an interdisciplinary manner. I was originally referred to Dr. Brenner for my cough due to a chronic phlegm issue and we wanted to be sure it wasn't playing a role in my heart issues. He advised trying medication and diet timing changes to see if that was affecting my lungs. He called to check if I experienced any positive changes.

Dr. Brenner has always been open with me and explained everything concerning my issue. Any questions that I asked, he promptly responded and I could call him at any time if I needed. So I'm very grateful that I have Dr. Brenner as my pulmonologist.

This doctor is wonderful. His staff, everybody in the office is pleasant, versus patient, and absolutely wonderful. Too bad the rest of your doctor's offices aren't like them. Thank you.
