We realize $1,000 is a “stop and think” gift.

For many of our members, $1,000 represents sacrifice and intentional budgeting to make a charitable gift of this size. That is by design. The goal is for each member to feel fully invested in and connected to their giving, and the transformational grants that result from it.
