That plan will usually emphasize conservative, nonsurgical care first, with surgery always being the last option.

Dr. Daniels recognizes and respects the value of a team approach. By utilizing the skills offered by many types of healthcare providers he is able to achieve excellent outcomes from his patient care.

I really like Dr. Daniels. I am new to this area, and getting a new ortho doctor that I could trust and like is a big deal for me. When my sister told me about him, I found he was really a personable person who actually is in tune with his patients.

Dr. Daniels is amazing...I knew he was an excellent surgeon, but didn't expect him to be so likable. Not only is he exceptionally competent, but he exudes confidence & friendliness. My primary care physician recommended him, and said he would sent his own mother to Dr. Daniels. I concur. I found Chelsea to be extremely competent & a great help as well, and both of them are always smiling.

Dr. Daniels is a very happy upbeat person when he treats you and spends time with you. He willingly explains answers to all your questions. I could not be any happier with an orthopedic doctor. I trust him completely with his assessments and advisement on how my treatment should be approached and handled.

I have recommended several friends to Orthoillinois.

Dr. Daniels came in with a big smile and a handshake. He asked me what had happened, listened attentively, asked me about my pain. When I said my balance was terrible he offered me his hand which I thought was nice. He then told me his diagnosis and that I didn't have to worry about hip surgery. In fact he said my hips looked good. What great news! He told me what he was prescribing and a timeline for my recovery. His nurse then told me about my prescriptions. Then I was wheeled back where I had left my crutches, wheeled to the door and helped out of the wheelchair and back onto my crutches. I felt so glad I had come and felt good about my recovery.
