About Us

We specialize in fracture and trauma treatment for children and adults, hand surgery, joint replacement surgery, sports medicine, spine surgery and general orthopaedic care.

Our Philosophy

The physicians of Phoenix Orthopaedic Consultants are devoted to providing the highest level of quality care and treatment of the musculoskeletal system in a compassionate and personalized way. This includes the bones, joints, ligaments, muscles and nerves. We specialize in fracture and trauma treatment for children and adults, hand surgery, joint replacement surgery, sports medicine, spine surgery and general orthopaedic care.

With the demands of our rapidly growing population, the practice has evolved into a multifaceted, subspecialty-oriented group, mirroring a nationwide trend. Today the specialty of orthopaedics is a highly technological field and our expertly trained members reflect the diversity of our profession. We possess subspecialty skills in trauma, spine surgery, sports medicine, adult reconstruction and joint replacement surgery.

We are community leaders in the integration of technology into our practice of medicine with a sophisticated electronic medical records and digital imaging system.

Some of our members are also leaders in healthcare on the local, state, and national levels. We have been recognized in local and national media.

Our first priority however, has always been and, will forever remain, the care of our patients.
