"I have been going to Dr. Rosenberg for 20 years. Always happy to see me and makes me feel comfortable around him. He’s a great listener and always seems to ask the right questions, the ones you are afraid to ask. I had my choice of other doctors but when you have to see a doctor about something so embarrassing as this and you feel that comfortable you stay with him. Thanks Dr. Rosenberg!"

"I did a televisit with Dr Rosenberg. He had reviewed my chart which was in the system. I explained my reason for the visit, he asked some questions which provided the details he needed to form an opinion, and he clearly suggested a plan for maintenance care. He was personable and explained medical issues in layman's terms. I highly recommend Dr. Rosenberg."

"I have been a patient of Dr. Fred Rosenberg’s for over 21 years. I went to him at the age of 23 when I was diagnosed with ulcerative colitis. Outside of three years when we moved out of state, Dr. Rosenberg has been my main doctor and advocate. He is extremely knowledgeable and personable and he always listens to me and works with me to come up with the best solution. He is a doctor I truly trust and can count on and that means so much.

"Dr. Fred Rosenberg has saved my life on more than one occasion! I am eternally grateful for his extraordinary knowledge, kind demeanor, great outlook, and dedication. His professionalism is a natural part of who he is! Dr. Rosenberg was recommended to me by one of my other doctors, so I knew he would be a wonderful doctor. Sure enough Dr. Rosenberg is fabulous. I have had many colonoscopies performed by Dr. Rosenberg, but over seven years ago when I was extremely ill and planning on taking a family vacation to South America, is when Dr. Fred Rosenberg first saved my life! The second time Dr. Rosenberg gave me the best advice was right before this Thanksgiving. It’s extremely upsetting to be ill, but to be ill before a vacation or holiday is an added stress. Thanks to Dr. Rosenberg not only was I able to take that once in a lifetime vacation in 2012 but this Thanksgiving with family and our first granddaughter has been memorable. I wish I could give Dr. Fred Rosenberg higher praise than he is awesome and wonderful! But take it from me, one extremely grateful patient, Dr. Fred Rosenberg is the best gastroenterologist! Thanks a million for all your wonderful care, Dr. Rosenberg. I can’t thank you enough for your dedication and time and professionalism! You are phenomenal!"

He did every test possible, listened to my concerns and has finally figured out my issue. He’s a gem."
