Dr. Rosenberg is a very compassionate and caring doctor. While most doctors are in a hurry to move on to the next patient, Dr. Rosenberg spends a good amount of time with me. He actually LISTENS to my complaints! He is very thorough and really tries to find a solution and reason for my discomforts. He explains things in simple terms. He makes sure I understand his instructions before I leave his office. He encourages me to call or text him if I have any questions. And he responds !

Dr. Rosenberg has been my doctor for a number of years and I have great confidence in him. We have tried different treatments as necessary and one recent discovery and treatment significantly reduced a persistent problem contributing greatly to my quality of life. Kindness, patience and skilled medical knowledge, the best combination. His staff is great, too. I would highly recommend him.

Presribed a drug that was recalled for being dosed at dangerously high levels, I had severe complications but they never returned my calls. Misdiagnosed my condition and refused to correct it. Books appts five months in advance. When I asked for another doctor instead, I got a nasty letter saying THEY were discontinuing ME as a patient and slandered me! BEWARE

I have always found Dr. Rosenberg willing to listen. He is very knowledgeable and open minded when I discuss alternatives (which do not always work out). All of these traits are important in any doctor.

Dr. Rosenberg listens and has empathy. He is very knowledgeable. He ask lots of questions and gave me examination in the same visit. It was refreshing to experience this level of professionalism in healthcare. His staff is also equally incredible. I highly recommend Dr. Rosenberg.

Dr. Rosenberg made room to see me next-day soon when I had an acute problem. He sorted through it with my, explained the steps we would try to alleviate it, and was very sympathetic and supportive.

Dr. Rosenberg is conscientious and willing to try different treatment methods. I have IBS and I had to try different things before I came upon what works for me. If you are willing to follow his instructions and try different treatment options, you will have a greater chance of finding relief. I feel better than I have in years and that is thanks to Dr. Rosenberg.
