Day One is a community-based nonprofit organization with a 25 year history of providing effective, high quality and culturally-sensitive public health education, intervention, policy development and environmental prevention efforts.
Day One grew out of a collective vision of concerned community leaders in 1987. Their vision was spurred by the drug epidemic in Pasadena and Altadena, especially among youth and in the Northwest area. Since then the organization has become a leader in youth advocacy and community health in the San Gabriel Valley.
Day One builds vibrant, healthy cities by advancing public health, empowering youth and igniting change.
