Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Nice doctor…knows his craft well
This was my first time seeing Dr. Ziermann. He was very easy to talk to and quickly determined next steps based on my issue. I was concerned because he’s taking over for my usual Orthopedic that I’ve known for decades who is on leave, however, it was a quick frustration free visit. He was very personable and friendly. My reservations are gone…

Not a very good Physician
Dr. Ziermann is not a good Physician. He doesn't care, he needs to lecture and talk down to his patients. Ziermann should be avoided

So impressive
Dr Ziermann is a thoughtful, rigorous and skilled doctor. He has great energy and really listens to his patient. I brought my son for a concussion and was greatly relieved after seeing him.

A must to avoid
HorribleHe refused to answer my questions, refused to show me my xrays in person (which I had requested when I first made the appt.). He just wanted to talk about what he thought, and refused to listen to any of my inquiries. I was accompanied by my husband, and we were shocked. When I asked him to show me which of the muscles surrounding the injured area needed to be addressed, he was put out. He then yanked my knee to inspect it. I screamed. Instead of apologizing, he just said - Oh you'll never get your ROM back in that area. Which wasn't true. I went home and iced it, addressed the issue myself, to fix what he yanked--and i'm back almost 90%.

Good doctor!
Dr. Ziermann understood my condition and was very helpful. He was very pleasant and polite. He knows what he is taking about, answered my questions and has me headed in the right direction for what I need to do next. I wanted to leave a review because I saw a couple stating that he was rude or arrogant and this was not my experience at all with him.

Best Advice and Explantaion
Awesome this is the best Doctor I have seen in 12+ years. He explained everything as osteoprosis is his specialty. I now understand my pain and the difference between osteoporosis and arthitis. I am full on now at 76. Thank you so much for your guidance. Just knowing and understand has made a complete difference in my life.

Dr Ziermann is a fantastic, talented and patient doctor. He has treated me for a severe concussion, and has enabled me to recover with his informative and helpful medical and personal advice. After such a life changing accident, I needed a well trained and thoughtful caring doctor - and Dr Ziermann is all of that and more. I highly recommend him.

Dr. Ziermann first diagnosed me with a dislocated finger and then informed me on my second visit that my finger was in fact fractured and then started examining the wrong finger. He was also very rude. I will not return to orthopedic associates

Dr. Ziermann helped our son who had a very complicated concussion. Dr. Ziermann really knows well how young atheletes need to recover. I am writing this review because I wish he was still located where we live. He was truly the best of what he does.
