April 3, 2018 Dear Patients,

In anticipation of a very slow time of year for my practice, there will be summer hours formed to compensate for this time. AS OF TUESDAY JUNE 5TH, 2018, office hours will be as follows.

Tuesdays and Thursdays from 9am to noon and then 3pm until 6pm. These will be my hours and there won’t be any exceptions made. These hours are necessary due to the very slow nature of summer time in Flagstaff and for the growth of my other business which requires more of my attention during these same summer months.

I realize that this may not be very convenient for all patients. I will also not be accepting new patients through my online scheduling. My practice is evolving into more of a wellness or maintenance type of patient and unfortunately that means for the average new patient it will require more care than I’m able to give at this time. Thanks for all the support that you give to me and my unorthodox practice here in Doney Park.

Very sincerely yours,

Dr. Brian Weathersby

Chiropractic Physician

  • "As a patient of Dr. Weathersby for the past 5 years I have been continually impressed by his treatment of not only the symptoms but of the cause of those symptoms. His knowledge base continues to impress me. He has treated my issues from running mountain ultras, body building competition, pregnancy, and now a specific type of arthritis. Thank you Dr. Weathersby!"
