Volunteer Requirement:
In order to make the Retreat a success, and keep costs low, we ask that each person volunteer before or during the retreat to distribute the workload so everyone can enjoy the retreat.

Please Note: We request that you prioritize clean-up options – we mostly food prep before the retreat so prep will be light but clean-up will be needed. Thank you!

There is a section on the attendee details form at online registration for you to note your volunteer preferences for the retreat. Thank you in advance for your help!
