Everybody from the girl that checked me in to the girl that took me into the room to meet with Dr. Mariani to the girl that did my x-rays, everybody was definitely a 10 plus. And I have been to this facility before and I would rate it one of the best in New Jersey and especially Dr. Mariani. He is very knowledgeable and very personable and I'm looking forward to seeing him again in the future for my knee shots.

At every appointment from our 1st visit in June through my 12 week post op session, Dr. Mariani involved me (and my wife) in every decision regarding my care. He provided alternatives and options at every step and was extremely thorough and professional.

Dr. Mariani it's wonderful. He tells you everything good and bad doesn't push you to do anything, but you make your own decision feel very comfortable with him.

Dr. John Mariani replaced both my knees. He is extremely competent and patient. He answered all my questions and listened to all my concerns and fears. I trust Dr. Mariani completely. He gave me back my life. I can walk now without any pain. He is truly my hero.

I've been seeing Dr. Mariani for several years. He preformed my knee replacement years ago. I was just in an auto accident and saw him to check on that knee since I was having pain. He is the best

I'd just like to say that Dr. Mariani did a fantastic job on my mom's knee. He not only explained everything, but he made her feel very comfortable about a surgery that she was very concerned about and awkward. And his complete support staff was all very supportive and very generous with their time. Thank you.

This was a positive experience. Everyone was professional and friendly. All options were explained and I'm confident this will be a successful outcome.

Yes, I think the one thing that could make it better when patients are calling in is to get rid of that recording where the woman is explaining everything that you do, knee, back, hip, that she goes on and on and on and there's no way to bypass that and that's at least a minute, a minute and a half right there. I think that if we were able to push something to stop that recording and go directly to where we want to go, that would be very beneficial to the patient.

Very pleased already have recommended this practice to a few friends

I was very satisfied that I got an appointment so quickly. I had called on a Monday and I got the appointment for Thursday. When I saw the doctor, he was just wonderful. He really helped me a lot. It was a year since I had gotten the cortisone shot and so far since I've had it this year, it's really helping a lot. And I want to say how wonderful his office staff is and also how wonderful he is. I'm very glad that I have him for my doctor. Thank you.

I trust Dr Mariani because he operated on my right knee 10 months ago and now i am relieved of pain in my knee but knew from my visit last year that both knees were bone on bone. Now I feel it is time to get my left knee operated on in order to have the same mobility my right knee gives me since the operation.

Yes, I was a little confused at the call that I received because I was in the car driving, but Mariani, Dr. Mariani, was wonderful. The staff was wonderful. I don't know what was going on in the car, but I just couldn't go press in the numbers. But I had a wonderful experience at the office and Dr. Mariani was, how would you say, he took the time with me, went over what my situation was, and I was very well pleased. So that's what I want to say. Thank you.

Dr. Mariani was very, very efficient, very knowledgeable, took time and explained everything very, very concisely, covered all bases. His crew, his staff, everybody in the office there were fantastic. They always answer your questions with politeness and efficiency. If you have any questions, you just go to them and they're always willing to help you. This entire episode was very well handled and I would recommend Dr. Mariani and his staff immediately to anybody.

Dr. Mariani is a very knowledgeable, passionate, dedicated, kind, just everything, everything good. He's really a one-of-a-kind doctor. It's just so refreshing to have him as my doctor, which I have had him as my doctor since before 2013. I don't know the exact date, but he is a gentleman. He's just, he's one of a kind. And I truly am grateful to have him taking care of me.
