National Second Opinion Program

Root Cause Psychiatry

Our caring professionals evaluate and treat The Whole Person.

We will do Whatever It Takes to help you feel well, recover your health, improve your relationships with others, and determine your destiny.

If you are being treated for depression, anxiety, bipolar disorder, or OCD but your symptoms have not improved or have only partially improved, you may be experiencing “treatment resistance.”

Feel better faster, at a lower cost. Through personalized precision psychiatry, a genetic test can reduce the cost of treatment and improve quality-of-life in patients with depression. And in patients with mood or anxiety disorders, three months following the use of genetic testing information, 87% showed clinically measurable improvement; and for those patients with two or more prior treatment failures, 91% showed clinically measurable improvement. Patients also reported significant decreases in medication side effects.
