Not sure about matt damon working with them...
I know of them because Justin Wren is a friend of a friend... i have a buddy "the pastor of disaster" who is an mma fighter, trainer, and a pastor... funny guy who works harder than anyone i know... after i saw Justin on joe' s podcast i talked to my buddy who confirmed Justin is an awesome guy with a real heart for the hurting... my buddy had even done a charity fight for this organization when he first started his charity...
And yes, Joe likes the herb... who wouldn't?
