Restoring the biology behind mental wellness.
Mental wellness is about more than brain chemistry. Your biology, including gut health, nutrition, inflammation, and immune balance, shapes mood, focus, and resilience. Led by Dr. Koichi Tanji, a naturopathic physician and licensed mental health counselor, our approach combines psychotherapy with biological assessment, cellular restoration, and restorative care.

Therapy and psychiatric care are essential, but they aren't always the whole picture. Biology, including inflammation, gut health, nutrition, metabolism, and cellular health, also influences mood, focus, and resilience. We assess and treat both the mind and the biology behind mental wellness.
Psychological evaluation combined with advanced biological testing, gut, genomics, toxins, immune and cellular markers, to uncover what's really driving mood, cognition and resilience.
