-### Continuing in Winter 2026

-We are trying something different in 2025-2026. We are modifying the traditional Champions structure to be more light-weight so that participants can engage at whatever level they can (rather than the full cohort-based model of usual Champions programs). Following the Fall 2025 events, **in Winter 2026 we will lead a 4-Part Series of Community Calls and Coworking sessions**, likely February - April. Details and registration coming by November 2025.
