About us 

Day One has over 30 years of experience in working alongside residents, young people, elected officials, and other stakeholders to strengthen and build healthy, vibrant communities by advancing public health, advocating for public policies, meaningfully engaging youth, and igniting community-level and behavioral change.


Through the years Day One’s work has earned the organization countless awards, an increase in grant funding, and most importantly key public health policy victories that help address issues of inequity, social justice, bias, tokenism, and social determinants of health among vulnerable, underserved communities.


The agency and its staff are noted leaders in youth advocacy, community engagement and coalition building, policy development and advocacy, and environmental health in the San Gabriel Valley. Our team is skilled in conducting outreach, facilitating community meetings, forming coalitions, and sharing, leading, and implementing community-driven strategies to prevent chronic disease and promote healthy, active communities through evidence-based policy and public health-oriented city/urban planning.



Our agency’s mission is to build vibrant, healthy cities by advancing public health, empowering youth, and igniting change.



Our vision is to create a healthy, connected, vibrant world.
