Wonderful Client Feedback

Dr. Diehl always listens and takes the most conservative approach for the injury rather than surgery first. He’s taken care of several of my sprains & falls. Highly recommend.


I really like Dr. Maurer. He is so down-to-earth and honest. I’ve learned to trust his advice and guidance because he cares about his patients.


Scheduling was quick, office staff was friendly and efficient and nurse and x-ray tech were friendly and thorough. Dr. Lessner was prompt and friendly. He made us feel comfortable and explained everything clearly and thoroughly.


This has been one of the best medical care experiences I’ve had, from our initial consultation to post-op visits to physical therapy. Dr. Diehl and his team are a very caring, friendly, and professional group. I had a left knee injury (meniscus and ACL tears). Thank you!!


Very impressed with Dr. Lessner. Very thorough and listened to me. He gave me multiple treatment options and involved me in the decision making. Highly recommend!


Dr. Diehl was very kind and caring. I don’t think there is a person in this office who is not professional and personable. They go above and beyond for their patients.
