About Us 

Day One is a nonprofit 501(c)(3) organization with a 38-year history of providing effective, high quality, and culturally appropriate outreach, education, and project development throughout the San Gabriel Valley (SGV).


Day One’s experience in advancing environmental goals throughout LA County is extensive. We most recently helped advance the approval of Measures W, A, and M. We have also been involved in the LA County Sustainability Plan, Advanced Energy Community, El Monte Stormwater Master Plan, San Gabriel Valley Regional Bicycle Master Plan, and the Puente Hills Landfill Park Master Plan, among other efforts.
