Great overall experience. Doctor is awesome.
Thank you for kind comment and high review. Have a great day.
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

Dr. Rosenberg is great. He is very busy but one is never left with the impression that he does not have time to talk with you about your medical issues and concerns. He takes the time to explain just what you need to know to optimize your understanding of your condition and what can be done to improve your health and comfort. All the while he has a laptop attached to his shoulder (smile) where he adaptly records medical information, something that not all doctors are able to do.

Dr. Rosenberg is a wonderful, caring, and patient doctor. I love it that he doesn't rush you or make you feel that your ailment is just nonsense and doesn't really exist. He listens to what you have to say very carefully and responds accordingly. He is very thorough and genuinely cares about your overall health. He explains things to you using terms you can understand. If you leave him a message, he always responds in a timely manner. I wish all my doctors were like Dr. Rosenberg!

Dr Rosenberg is an excellent, caring and professional doctor. He shows empathy towards his patients. I see it first hand. I trust Dr Rosenberg!
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.
Los Angeles, CA |
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.
Glendale, CA |
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.
