At the Integrative Pain Center of Arizona our professionals are specifically trained to evaluate and to treat painful illnesses! They have devoted their practices to that end.

We work with you to define the most accurate diagnosis, to create a treatment plan that integrates whatever resources may help, to empower you to ease pain, to reduce pain related disability, and to help you achieve the highest possible Quality of Life through the creation of interdisciplinary partnerships in a caring environment where research and education blend with clinical practice.

Pain is complex, so our professionals apply and study the multidisciplinary model of health care.
