Valerie is on a mission to help organizations create workplace cultures where people thrive. Above all, she loves the thrill of seeing people come to life at work – with renewed purpose, engagement, and initiative.

Previously, she served in the United States Air Force where she instigated a culture change movement that transformed a bureaucratic unit into a powerhouse of creativity and innovation, leading to intelligence breakthroughs. She didn’t stop there, though – a variety of game-changing programs adopted by the Air Force and the National Security Agency can trace their origins to her fearless willingness to challenge the status quo.
