Welcome to A-1 Orthopedics!   

I am Haagen A Diener, MD.  I am an Orthopedic Surgeon who provides a wide range of orthopedic medical services to the Phoenix-metro area.  Our office is located in Tempe just down the street from Banner Desert Medical Center.  I am double board certified in both Orthopedic Surgery and Orthopedic Sports Medicine.  I have been practicing in Phoenix since 2001.  

The mission at A-1 Orthopedics is to provide top notch, up-to-date orthopedic care in a compassionate, supportive and informative environment.  My goal is to have each and every patient leave the office with a full understanding of their diagnosis and personalized treatment plan.  

The office is open 5 days a week and we are seeing patients. Our contact information, address and a map to the office can be found at the links listed in the left column.  Call for an appointment today!  (480) 299-7908
