When I first contacted them about my right knees, the staff listened carefully to me and communicated to Dr Klein and got back to me with a closer appointment as I felt with knee pain 16 years and I was unable to put any weight on it.

When I arrived for my appointment I did not have to wait at all—I was seen promptly upon arrival. The receptionist and nursing staff were kind, friendly, helpful, and very professional, which made the visit comfortable from start to finish. Dr. Klein provided excellent care and was extremely knowledgeable, professional, and empathetic. He took the time to listen to my concerns, explained everything clearly, and never made me feel rushed. Overall, the care I received was outstanding.

Dr Klein went above by notifying my Private Health provider of my on going treatment. He has changed direction of my medical treatment for other conditions.

Dr. Klein did both my knee's 17 years ago, I have recommended to him to many of my friends. I would not see anyone else but him.
Nov 12, 2025
I was a bit upset as I came with a question about pain and bursitis. While I know the doctor does not treat that, I was inquiring if I needed a hip replacement. When I stated I was having some pain in the front of the hip, it seemed that I was dismissed. I was somewhat disappointed.
Nov 10, 2025
I am very satisfied with this hospital and all the doctors I have seen, thank God. I have absolutely no complaints about it. I am very grateful to God and for the excellent maintenance of the hospital. Thank you very much, and have a good night.
Nov 10, 2025
As always, my visits with this provider have been exemplary. That is the reason I returned after my knee replacement 15 years ago. I could find no other doctor I felt has comfortable and safe with.
Nov 10, 2025
The front reception staff were very helpful along with the reception staff and the back by physiotherapy. And the person that did the initial evaluation was very thorough and very professional. So love the place.

Taken a couple of x rays before seeing the Doctor. Not so sure if he had a chance to see the X rays. Obviously, he didn't even mention about it. Very disappointing.

Dr. Klein is a great Dr. He is very personable and cares tremendously about his clients.
