Collaboration with other organizations can build your organizational capacity, amplify your impact, and help you serve more people – but only if you get it right. Successful collaboration starts at home – with your board and senior leaders building the right internal culture, competencies, and systems before you approach potential partners.

Join Liz Weaver, former Co-CEO of the Tamarack Institute, and Linda Mollenhauer, Chair of Ignite NPS, as they share practical stories and ideas to help you choose the right collaborations, show up as a strong partner, and avoid common pitfalls. They will draw from free resources in The Collaborative Organization – tools you can use right away.
