Glenn is a social entrepreneur, advisor, and teacher helping purpose-driven people and organizations thrive.

Driven by a lifelong commitment to community and an entrepreneurial instinct to build what matters, Glenn has spent more than 40 years leading and strengthening mission-based organizations. His work has focused on transformation: rebuilding what is broken, strengthening what is struggling, and creating what does not yet exist.

He understands the real challenges leaders face because he has lived them. That experience shapes a practical, deeply collaborative approach grounded in partnership rather than prescription. Glenn does not simply offer advice and walk away. He believes the best ideas emerge when people are invited into the process, communities are engaged, and the right collaborators come together around a shared purpose.

Glenn’s mission manifests itself in a number of ways. GKollaborative is his strategic advisory practice helping small and midsize nonprofit organizations grow stronger through planning, fundraising strategy, governance support, and idea incubation. LUNA Experience is an international learning community for mission-driven professionals and organizations seeking to learn, connect, grow, and accelerate their impact.
