Dr Rosenberg is hands down one of the best doctors I have been blessed to have! He is always relaxed and friendly, never rushed while maintaining the right level of professionalism. He is comfortable answering my not always easy to talk through questions while methodically taking his time to breaks things down so that I can understand (and he first makes sure to understand my questions and why I am asking them). In addition to all of that, I have 100% confidence in his abilities and my health today is a testimony to his care at the most critical point of my health journey involving cancer. I would and do recommend him to others for their care when battling cancer. I strongly recommend him to anyone unsure about their care.
