Psychologist, executive, and national voice on addiction and homelessness — designing systems that move people from instability to independence.

Invite Dr. Hayden to Speak Explore Her Work

A clinician who builds the systems, not just the caseload.

With more than 22 years of clinical experience, Dr. Julie Hayden leads a network of organizations spanning residential recovery, transitional housing, community counseling, and higher education — and co-created the frameworks that hold them together: the Rhombus Model™ and the Protect → Prepare → Propel™ continuum of care, developed with her co-founder, Dr. Ray Hayden.

Her work has drawn national attention for one reason: it works, and it can be taught, measured, and repeated.
