Beyond business

My volunteer work as Board Chair of the Montreal Community Cares Foundation continues to be a source of extraordinary learning, leaping and soaring. I get to share and work with amazing youth, delivering goal-setting, resilience and other skills-based workshops. What I’ve seen and experienced only serves to reinforce my belief in the power of a coaching approach at every age.
