The Base Power Learning Community* invites you to watch a learning webinar series many months in the making. Take a look below to watch videos and sign up for more information on two upcoming trainings.

Base-building work touches every department and aspect of an organization’s work. Multi-entity organizations (organizations that operate 501c3, c4, and other legal entities together to build power for their communities) face unique and complex challenges engaging and managing members across legal entities.

Because of this complexity, effective base-building strategy requires a holistic approach and support that integrates the advice and best practices from different perspectives of organizational development and field. Learn from members of our Base Power Learning Community, which has studied the latest and most effective strategies for base-building across multiple legal entities.
