Mission & Focus Areas

The foundation’s mission is “Uplifting community practices that build health and connection among people and place.” Its website identifies funding priorities that include opportunities for everyone to live a healthy life, strengthening the culture, policies, and practices that support a healthier Hawaiʻi, and building community health ecosystems.

The 2024 grants included support for health sciences education and for organizations serving communities across Hawaiʻi. For example, the University of Hawaiʻi Foundation received funding for a program to build learning innovations for future doctors and interprofessional health sciences education and simulation. Several Hui partners received grants for operational expenses. The grantees’ own descriptions illustrate their work: Five Mountains Hawaii says it provides biopsychosocial services in North Hawaiʻi, with special emphasis on Native Hawaiian health disparities; Waimānalo Health Center describes its work as providing primary and preventive health services, particularly for Native Hawaiians and medically underserved people; and Kōkua Kalihi Valley describes its mission as advancing health, inspiring healing, and fostering reconciliation through relationships that honor culture and place.

Grantmaking

In filing year 2024, the foundation reported 19 grants totaling $2,068,000. Grant amounts ranged from $2,000 to $1,200,000, with a median of $50,000. The largest grant was $1,200,000 to the University of Hawaiʻi Foundation for building learning innovations for future doctors and interprofessional health sciences education and simulation. Other notable grants included $100,000 each to Five Mountains Hawaii, Kōkua Kalihi Valley Comprehensive Family Services, and Waimānalo Health Center, all for operational expenses as Hui partners. Kualoa Heʻeia Ecumenical Youth Project, Ma Ka Hana Ka ʻIke Building Program, and The Food Basket each received $75,000 for operational expenses as Hui partners.

The foundation’s website says it moved away from an open grants process in 2019 and would no longer accept grant applications, instead using a cohort model with a small group of nonprofit partners. Its website describes a 2019 Hui of 10 organizations and a second Hui announced in 2025, comprising eight organizations. The 2024 filing lists no application deadline and refers applicants to Statement 10 for forms and materials and Statement 11 for award restrictions; it lists HMSA Foundation as the contact.
