Dr Diemer was fantastic!! She actively listened to my explanation of symptoms and included me on decision making about plan for next steps. Mikhayla was super helpful at discharge by offering to help schedule appointments for MRI and PT.

Dr Diemer was outstanding during my visit. She delivers news I was not expecting and was very sympathetic and kind when I became emotional. Her advice about future treatment of my knee was very valuable and the treatment she provided helped me overcome the pain and regain normal activities. I hope to see her again!

From the checking desk to the PA to the nurse that checked me in and into the doctor, all work extremely exceptional. A special kudos to Dr. Diemer, who was extremely bright, thorough, caring, and who related to me with kindness and compassion. I can't say enough about how wonderful she is and the staff.

Dr Diemer is outstanding. When she enters the room she clearly has reviewed my records, summarizes my history to bring us to the current moment then listens carefully, presents options and advises. As a retired physician myself I can state with confidence her performance could be a model for all of us.

Both the doctor and the assistant should be noted for outstanding care.

I feel that Dr. Diemer has always spent time listening to my concerns. Besides being very professional, she has a friendly demeanor that really helps me with my 'white coat syndrome'!

Mar 24, 2026
Dr Diemer and her staff used the information from previous testing and listened closely to the current findings before making any decisions. We discussed the options which led to working to get to the root cause vs treating symptoms. Tests were ordered immediately to help confirm the diagnosis and a specialist identified to help once the testing is completed. Oftentimes this would have taken multiple visits.

Front desk staff both scheduling and post scheduling made our time very reassuring and comfortable.
