Dr Mann provided necessary, arthroscopic surgery on my knee. Surgery was successful and I had minimal pain or discomfort. Recovery was good and quick to heal. Follow up appointments were great and expect full recovery and function. Dr Mann was kind and considerate, explaining throughly explaining the surgery and recovery. I highly recommend his medical services.

Great experience! Appointment was quick and on time. The doctor explained everything so I could understand the diagnosis and wasn’t interested in me having to take extra steps that were not needed.

When my daughter broke her ankle, we landed in the caring hands of an amazing orthopedic surgeon, Dr. Mann. They got us in quickly, casted her with ease (thank you Jenn SB!) and made the whole process fun, which was a game-changer for my anxious 13-year-old. Their approach was refreshingly conservative, focusing on her body’s natural healing rather than rushing to surgery. Plus, the cost was surprisingly manageable, even without insurance. I just wish we’d skipped the urgent care detour and gone straight to them! Truly top-notch care.

I had to see Dr. Mann since my doctor was full. He was awesome because treated me like an equal, since I have a medical background. I appreciated he had an student Intern because my femur break was a rare one. I loved how he showed myself and the intern the break on my MRI for educational knowledge. I thought he was very approachable and quick to explain things.

Dr Mann is awesome! He did a total joint replacement on my shoulder and everything worked out great. He is very thorough when explaining what needed to be done and how he would repair it. I highly recommend him. His staff has always been helpful and pleasant to deal with.
