Yes, Dr. Granowitz is an excellent doctor. I have plenty of confidence on his care and I have only prized for him. I'm very proud to be his patient. He always is looking for me to be as comfortable as possible and always finding the best ways to do things with me, always include me in every decision. So yes, he's the best provider I have so far and I've been with him for close to 20 years.

I felt he was paying attention, had long experience and because of his demeanor, felt I could totally trust him. Best doctor I've seen in a long long time!

He was very good and if the other hospital forwarded my info it would have been far more productive

Dr. Granowitz was extremely helpful. He explained everything that we asked because my sister was there with me. She's my caregiver. I would highly recommend him. I couldn't be happier with our phone's visit.
