How should a start-up membership organization recruit, actively engage and grow membership over time, while also playing a larger public education role? That was the challenge presented by APPA, a brand new organization seeking to advance safe, effective and accessible psychedelic medicine services for behavioral health. We began by working with the board to develop APPA’s branding and website as a robust platform for advancing public education, advocacy and community.Collaborating with the executive team, we then designed and developed a content strategy and informational website and a variety of community engagement tools, including newsletters, surveys, and online convenings, as well as educational content for members and the public at large.
