Doctor . Nurse, radiologist and staff . All excellent . And compassionate
I could never have gotten any better service. Dr. Klein is a wonderful physician and very kind and very thoughtful. And I had experience with him and some surgery about seven years ago. And I'm back for the same surgery, but the other leg. And I just adore him. I think that he's a wonderful person. The whole staff was wonderful. Everybody was very sweet and kind and thoughtful. And I just loved everybody. And I'm very happy with that.
The whole entire experience from my initial visit through my surgery and my three follow-ups was superb with Dr. Klein and with his physician's assistant as well. The front desk staff and the x-ray technicians were also highly professional and accommodating. Just a great experience. I have recommended Dr. Klein and Hackensack Meridian Orthopedics, in general, to two or three people since my experience. Thank you.
Cortisone injection working so far. Thank you.
The doctor and staff are very cordial. The doctor listens to your concerns about your medical situation and provides easy to understand answers. He is very thorough and makes you feel at ease during the exam and afterward. He is a top notch doctor.
