I've been with this group for over 25 years. Michael Grassia, hands down is the best I've seen. I've had a kidney transplant for 40 years and Dr. Grassia is compassionate, caring and goes over every single aspect of my care. I would NEVER go anywhere else. His nurse Susan is the most conscientious, and detail oriented person I have ever met. Not one complaint.

More concerned with himself than the patient. You can do much better than dr. Grassia

I saw Dr. Grassia for the first time while i was a patient in the hospital and then followed up with him in his office. My wife loved him! He spoke with me every day while in the hospital and if my wife was not present, he called to update her on my condition. I had to start on dialysis and he took his time going over all the information and answering any questions I or my wife had. His nurse is one of the best I've ever seen. If you call the office, you get a LIVE person and a call back the same day. During a very difficult situation, Dr. Grassia and his team made it a little easier. Would highly recommend him.
