“I like Dr. Rosenberg for several reasons.  First, he listens.  He doesn't assume or disregard the patient's information or knowledge of themselves.  Next, he cares about his patients.  This was apparent from when we first shook hands to going through our appointment to when he walked me to see a member of his staff and he thanked me for coming in.  He's also humble while knowledgeable.”

“Dr. Rosenberg really cares about his patients. He did all the proper testing, then prescribed medications. He did personal follow ups which was great. Anyone who suffers from IBS or any digestive issues knows how life altering the problem can be. I'm really happy I found Dr. Rosenberg.”
