In this episode of Leaders Coaching Leaders, Sylvie Arseneau turns the tables and hosts a rich conversation with Peter DeWitt and Michael Nelson about their upcoming book, Lead Collectively: From Belief to Action to Impact. Drawing on 15 months of collaborative work with over 50 school leaders in New Brunswick, the discussion explores how collective leader efficacy can be broken down into shared understanding, joint work, and evidence of impact. Sylvie brings a unique lens as a former vice principal and New Brunswick Lead co-chair, asking incisive questions that reflect the real challenges and aspirations of today’s education leaders. The episode dives into how leaders can use formative and summative data to guide their practice, build coherence across systems, and foster meaningful professional learning. Listeners will gain insight into how to move beyond belief to action, how to create space for reflection and growth, and how to lead learning with confidence—even when the answers aren’t clear. This episode is a must-listen for educators committed to building capacity and driving student outcomes through intentional leadership.
