Our studies

We use trusted methods to deliver research with real-world impact.

All NHHRI studies are grounded in our commitment to culturally responsive, community-led research. Our work is guided by a national Leadership Council of experts and supported by a tiered network of Hispanic-serving providers across the U.S.

Research projects are overseen by our Institutional Review Board (IRB) to ensure ethical, community-informed standards. We also offer technical assistance to frontline partners, expanding access to quality research among underserved providers.
