From humble beginnings as a blue-collar paper mill employee in Mississippi, Mack's path to becoming one of the top corporate comedians and humorous motivational speakers in the country was a circuitous one to say the least. He was an award-winning newspaper reporter, taught karate after earning a black belt, and finally made a career of his true love, making people laugh and having a positive impact on their lives. As a performer, he's appeared on numerous TV shows, including The Tonight Show with both Johnny Carson and Jay Leno, as well as acting roles on many dramas like ABC’s The Guardian and JAG. As a writer, he's won a prestigious fiction-writing contest, and was handpicked by Bill Maher for the writing staff of ABC'S Politically Incorrect. He's a two-time cancer survivor who speaks at dozens of survival celebrations every year, and has also survived a harrowing stay in an African prison, not to mention “the sharks in showbiz who stab you in the front!" Instead of brooding about his misfortunes, he does the opposite and shares his goal-achieving secrets with hilarious, moving stories about the challenges he's overcome to reach his goals.
