COMMUNITY VALUES


Confidentiality and Sacredness
You'll meet people who are figuring out next steps, pivoting, and testing big ideas. To create a candid, safe space, attendees and topics discussed are off the record.

Spirit of Service
A rising tide lifts all boats. Instead of asking, "What's in it for me?" our members ask, "What can I do for someone else?"
