Meet Your Philosopher
Brian Johnson has spent half of the last 25 years as a Founder/CEO and the other half as a philosopher.
He’s studied Socrates in Athens, Jesus in Jerusalem, Marcus Aurelius near the Danube in Hungary, and Rumi in Konya, Turkey—and integrated that ancient wisdom with modern science into a scientifically proven protocol that changes lives.
Brian is featured in the documentary Finding Joe and is the author of Areté: Activate Your Heroic Potential. He has trained elite performers—from 4-Star Generals and Naval Special Warfare commanding officers to Marcus Freeman’s Notre Dame Football Team and Luke Donald’s European Ryder Cup Champions—alongside tens of thousands of everyday Heroes from every country in the world.
