Does your community have a local celebrity, such as a news personality or elected official, who has been open about their infertility journey? Invite them to attend and perhaps act as your MC.
Invite sponsors to make announcements, such as awards, top fundraisers, or to draw door prizes.
Keep your program and onstage announcements short and varied. Have a script and timeline. Have multiple people on stage (with quick transitions) to keep attention. Have visuals if possible (example, signs for award winners to carry on walk).
Walk chairs and key volunteers – you will be busy! Delegate as much of this as possible.
If you are going to take pictures, do it off stage to keep things moving.
