The E3 Leadership School

The purpose of the school is to teach in-depth the Engage, Empower, Encourage (E3) framework to dramatically shorten a person’s learning curve to reaching their full leadership potential.

The school distills the core leadership principles from Marc Koehler’s 30+ years of experiences as an Officer in the US Nuclear Submarine Force and turnaround CEO for struggling businesses and what he used to create strong teams.
