Health Advisory Boards
Since she didn't do it herself, I'll add that one coalition coordinator I support got invited to serve on her county Public Health Advisory Board, representing prevention, family supports, and positive youth development. Previous board members were mostly doctors and healthcare officials, so her perspective has been a valuable addition to their decision making process, and it's let to more opportunities to participate in public education and outreach. Chances are your local board doesn't have a prevention person either, so it could be worth asking if there's a vacancy.
