Mark Guay works with men standing at life’s thresholds, moments when the familiar ways of running a company, fathering, and living no longer fit. An adoptee and survivor of childhood domestic violence, he knows how ancestral burdens live in the body and shape the future, and how meeting them directly can change the course of a family and a business.

For over fifteen years, Mark has coached leaders from Amazon, Goldman Sachs, Slack, Etsy, Tatari, and JP Morgan. He is the creator of The Inner Authority Method and the voice behind Dad Notes, blending archetypal men’s work, Internal Family Systems, and leadership strategy to help business-leading fathers lead in a way that breaks old patterns and builds the kind of future their children will thrive in.

Mark holds a Master of Science in Education, is a Certified Integral Coach®, Hogan Assessments Certified, and has trained extensively in IFS.
