Chris Mosher has dedicated his life to helping people shatter the self-imposed ceilings that keep them from being the best versions of themselves. As co-founder of Liminal Systems, Chris has developed a unique blend of experiential group and individual work utilizing a grace-and-truth model that steps people into both challenge and empathy during in-depth weekend retreats, peer-to-peer group settings, and personal coaching.

Since 2005, Chris has worked with CEOs, Pastors, Professional athletes, artists, and others to work through mental blocks that hold them back from creating the life they truly want and envision for themselves. In 2019 he created and launched “The Unknown Journey”, a weekend event that challenges men to step into radical honesty, healing, and power. He has also developed a year long group program that facilitates teams into deeper levels of authenticity, communication, and effectiveness.
