I was in the waiting room and witness Dr. Janzer yell and reprimand an employee in front of the staff and the entire waiting room. It was very unprofessional. I hope he doesn't treat his patients this way.

I'm glad my primary doctor referred me to Dr Janzer. The knee shots he gives me works really well. Dr Janzer is never in a rush and always makes time to answer my questions. His staff is efficient and friendly! I highly recommend Dr Janzer and staff!

I had knee replacements that never stopped hurting. Three knee doctors just shrugged their shoulders. Dr. Janzer was able to tell me other places in my body where I was also having pain. He was exactly right. He felt the pain was coming from discs in my back. He went into detail on how it worked. He was the only doctor who ever went into such detail and suggested a pain specialist. I was very impressed and would go back. It was the 1st time someone actually tried to help me with my pain issues

After a fall on the sidewalk in early January I was rushed to the emergency room by ambulance where the on-call doctor was Dr Janzer. I was operated on by him and was told the following day that I had broken my femur bone in my left leg in 4 places . The care from that I received by Dr Janzer was at best, sparse to say the least. His concern and professional service rendered along with poor communication with his office staff was bad. There are better sources for medical care available.

Left my husband sitting in the waiting room for 6 hours without giving any status or aftercare instructions.

Dr. Janzer was a doctor I went to for a second opinion. I ended up staying with him because of his specialty and knowledge of the knee. He always takes the time to answer my questions and assures I understand the pros and cons of any treatment. He called me personally a couple of days after my surgery to make sure everything was okay and to answer any post op questions. He is experienced, knowledgeable and compassionate, and put me completely at ease. I recommend him to anyone.

This man single handedly improved my way of life dramatically. I have a life threatening genetic disorder called Marfan Syndrome and unfortunately suffered with a severely injured hip for 8 years. This man listened to me, and paid attention when no one else would. I can't thank him enough for everything he's done for me. If you need a hip or knee replaced I HIGHLY RECOMMEND this man! You'll be in fantastic hands far better than MAYO, CORE, or any other facility or physician. Thank You!
