Dr. Law, is an excellent and caring doctor who really considers the patient as a whole. Her recommendations and suggestions have helped my father live a life filled with dignity. She does not judge, and is willing to answer all questions.

I've been going to Dr. Leong for the past 5 years for liver-related issues. She's incredibly knowledgeable, understanding and personable. Would definitely recommend.

Review for Dr. Leong

Very friendly and knowledgeable . Took the time to answer all my questions and was very patient and thorough. No rushing at all. He’s at Mt. Sinai. I appreciated that he accessed my MRIs at NYU Langone.

Review for Dr. Itzkowitz

Laughed at me when I tried to explain different symptoms that I was there for. Dont waste your time with this doctor. Would not answer any questions I was asking. Staff such as the nurses are so very helpful and kind too bad he is not the same way.

Dr. Grinspan is an outstanding physician. He treats patients with concern and caring. He explains everything to the patient and to their family. He lets you know that you and he are working together to solve your problem.

Review for Dr. Grinspan

By far the best doctor I've seen yet. Prompt, super friendly and if I didn't live in Florida, I would see him. I went to him for a third opinion and they gave me the answers. Always in contact with them. Couldn't ask for a better doctor.
