I recently gave a talk at UC Irvine on my book, Toward the Healthy City, and we had close to 200 people turn out, including many community members from the City of Santa Ana. Santa Ana is one of the sites for the Building Healthy Communities (BHC) initiative sponsored by The California Endowment. I also participate in a half-day workshop organized by Professor Michael Montoya, students and community organizations working in both the Santa Ana and Long Beach BHC sites. The folks organizing for health equity in Santa Ana are doing amazing work, particularly America Bracho of Latino Health Access. America is one of the most dynamic and inspirational community organizers and public health leaders in the United States. We talked about the importance of and difficulty to sustain long-term community-university partnerships and the critical role of local knowledge for addressing health inequities, something I wrote about in my first book Street Science. In particular, Latino Health Access has trained community leaders through their Promotores model, and these folks (mostly women) are some of the most important experts on what it will take to build a more equitable and healthy community. I learned a lot from America and enjoyed our conversations about how to truly work for a more healthy and socially just city that address the specific needs of Latinos, people of color and everyone. I truly look forward to working closer with her team to help build a more equitable and healthy Santa Ana.
