William Muir MD spine surgery has an established reputation for excellence that stems from high-quality training, extensive surgical and conservative-yet-progressive treatment approach. We are dedicated to using the most appropriate, comprehensive orthopedic expertise in the service of our patients. Rather than just treating "the symptoms" 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. Due to Dr. Muir's background as a physical therapist, conservative treatment is well understood and can be tailored to the patient. We pride ourselves in the amount of time and education we provide to each patient. Dr. Muir has limited his clinic days to no more than 20 patients a day to provide adequate time to accurately treat each problem. Our office truly cares for each patient and only offers care that we would offer family members or friends with similar problems. Unless the patient's problem is dangerous, we exhaust all conservative treatment before offering surgical options. We truly put the patient first and paramount.
