The Walsh Approach has benefitted patients and is practiced by physicians around the world. The protocol for testing and diagnosis is based on the research of Dr Walsh and his famous theory of the "Five Biotypes of Depression."

Dr William Walsh's research and dedication has opened up a new paradigm of thinking in psychiatry. Nutrients play a critical role in balancing serotonin, dopamine and norepinephrine. We are deeply grateful for this protocol that gives doctors and patients great hope for treating depression and mood disorders naturally.
