Evidence Is at the Heart of What We Do

We’re committed to addressing the root cause of autoimmune disorders rather than prescribing band-aid fixes, providing a sustainable solution for healing autoimmune disease.

An Approach That Works


We lead with compassion. From day one, our Care Team makes sure members feel heard, seen, and understood. We listen deeply to ensure the member is in the driver seat and at the center of their care experience.

Unique, Holistic Care

Alternative means thinking outside the box. We break convention and think at the intersection of ancient wisdom and cutting edge science, offering integrative care that is unique and holistic to you.


Individual, but never alone. Deep healing can occur when you have a support system. We believe community is medicine and have the research from our programs to prove it.
