Over 20 Years of Diverse Experience

Ohana Healthcare Partners is an innovative consulting agency deeply rooted in behavioral health and driven by passion and understanding. The company was founded by Eleanor Castillo Sumi, drawing on over 20 years of diverse experience in public and private sectors, spanning roles from direct service provider to executive leader.

Empathy-Driven Innovation: Merging Lived Experiences and Professional Expertise for Holistic Behavioral Health Solutions

A unique perspective shapes the ethos of Ohana Healthcare Partners, that of a first-generation Filipina born and raised in rural Hawaii, where mental health stigma is prevalent and access to services is challenging. This background infuses our approach with a deep understanding of the cultural, societal, and environmental factors that influence mental health and access to care.

Our empathetic understanding is further enhanced by personal experience with the impact of mental health and substance use disorders on families. These lived experiences inform our partnerships with private and public sectors, guiding us in designing and implementing behavioral health programs that treat conditions and address the social drivers of health.
