Jim is the creator of Culture OS™ (Culture Operating System), a pragmatic framework that defines how leaders make decisions, set standards, reinforce behaviors, and close commitments so work actually gets done—without heroics, bureaucracy, or endless meetings. His approach bridges strategy and execution, giving leaders simple operating rules that scale across functions and industries.

A dynamic and engaging speaker, Jim blends real-world case examples, behavioral science, and sharp business insight to challenge conventional thinking and equip leaders with tools they can use immediately. Audiences consistently describe his sessions as practical, provocative, and refreshingly direct.

Jim’s mission is simple: help leaders build organizations that don’t rely on luck, personality, or heroics—only clear standards, strong decision rights, and disciplined execution.
