Excellent doctor, exemplary. This is long overdue. He treated me about 10 years ago for an infection which was taking a long time to clear. He convinced my insurance provider to cover a treatment that hadn't yet been formally approved, but was known to work. After a few months, the Insurance provider wanted to stop paying; it was taking too long. Dr. Rosenberg asked for just another month or two, he was confident we were almost there and he was frustrated with the insurance provider. When they stopped altogether, he found another way to get it, and he was right: that two months more did the trick, and the infection cleared. I've been HBV free for ten years now, thanks to that extra effort on his part. He fought the system for me. We need more like him. Thank you Dr. Rosenberg. -(Dave)

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 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.
