Our Practice


We make every attempt to identify "the source of the problem." this allows us to be more effective in treatment and to accurately tell the patients what their options are including the pros and cons of each option.

Our office truly cares for each patient and only offers care that we would offer family members or friends with similar problems. we exhaust all conservative treatment before offering surgical options. We put the patient first and paramount. 

William Muir, MD, spine surgery coordinates treatment plans that are individually designed for each of our patients.
