Isaiah P Hardcastle Leiutenant Colonel, United States Marine Corps (Ret.) A veteran of several still classified operations from late in the Vietnam war, Col.

Colonel Hardcastle’s military style business coaching techniques have been the subject of much controversy, however he remains unrepentant, “Dammit, any executive who can’t chew his way out from inside a sewn up buffalo carcass inside 3 minutes just ain’t worth spit!”
