This article reports on the community-based participatory research (CBPR) process of a 3.5-year study documenting lesbian, gay, bisexual, transgender, and queer (LGBTQ) community members' perceptions of local LGBTQ communities on the Central Coast of California. This three-phase study consisted of online and paper-and-pen surveys to analyze community strengths, challenges, priorities, and feelings of connection; collaborative interpretation of survey results through community forums; and a regional "LGBTQ Summit" to envision and initiate data-based actions to address community priorities. The focus throughout the project was on establishing collaborative partnerships to plan and guide the project, cultivating community participation in interpreting and disseminating findings, and honoring diverse LGBTQ community members' voices through data-driven community action. This article documents lessons learned about building and facilitating community-university partnerships, organizing and maintaining a sustained community research collaborative, engaging community participation, and ultimately, creating lasting, community-driven interventions.
