Eric Hansen, MD


Dr. Eric T. Hansen received a BA in Philosophy from the University of Notre Dame. He completed his MD at the University of Missouri, and he completed Psychiatry Residency training at University of Arizona. Before joining the team at Sierra Tucson, he served as Assistant Clinical Professor with the UA College of Medicine. He also served as consultant psychiatrist for the University of Arizona Athletic Department, working with college athletes.

Dr. Hansen believes that in recovery, there is an essential need for each patient to develop a detailed positive vision for self-actualization.  Modern pharmacology is often a powerful tool, but it is only a small portion of the journey.  He enjoys live music, skiing, and riding his mountain bike amongst the Saguaros.

The time spent at Sierra Tucson was the true beginning of my journey. Not only did I overcome my addictions, but I began to focus on the root causes that created my compulsions. I understand myself so much better now.
