Lackadaisical, uncaring, condescending, besides a very disrespectful non-helpful front office staff. Read other reviews - take heed. Just find another office and doctor and pass on this terrible experience. My insurance carrier concluded the same...

Very nice man, helpful staff.

Dr. Klein literally saved my son's life! He fought to have the hospital admit him immediately instead of waiting, performed emergency surgery that very night and 3 more in the following month to remove staff infection from my son's knee. When the hospital floor doc wanted to drill into my son's bone to make sure there was no infection, Dr. Klein assured me that wouldn't happen, and went toe-to-toe with the floor doc, letting him know in no uncertain terms that he, (Dr. Klein) was the specialist and my son's doctor, not the floor doc, and there would be no drilling into the bone, as doing that would surely cause infection in the bone! Dr. Klein is very honest, tells it like it is, and is very, very good at what he does. And he stands his ground in a very professional manner! I trust him implicitly!

Highly recommend Dr. Klein. He is very personable, to the point and has a great personality. I had a torn meniscus and he repaired it in a week. I feel great and Dr. Klein called the evening of the surgery to see how I was doing. Rare for a Dr. these days. His office manager Selene, goes above and beyond to make appointments and answer any questions. I moved to AZ 2 years ago and feel like I have known Dr. Klein all my life. He is thorough and the kind of Dr. you would want. I first started seeing him for my knees, he gives pain free cortisone shots and knee lubricant shots to relieve the bone on bone feeling. You can't go wrong with Dr. John Klein!!!

I broke my wrist in a quad accident. I did not have any insurance and could not find anyone to see me. I finally called Dr. Klein's office and they squeezed me in that day. He treated me in a kind and professional manner. I am extremely grateful for Dr. Klein's excellent and professional treatment. I would highly recommend Dr. Klein to my friends and family. One very satisfied patient!

i had bursitis and was able to get appointment same morning i called. office staff not friendly but that is generic to all doctor offices. they insisted i get five x rays before appointment. doctor spent only two minutes with me and cursorily looked at only one x ray. he wanted to give me cortisone shot but i wanted time to think about it and he was ok with that; did not try to pressure me. he did ask me if i had any questions and answered all my questions satisfactorily. he seemed competent and is orthopedic surgeon. when i called after an hour from my first appointment asking for another one to get shot the office staff said there was no appointment for another week even though it would take only a minute for him to give shot
