"We relaxed as soon as he hit the stage," is a comment heard quite often after one of Mack's uniquely entertaining and motivating presentations. After nearly 30 years as a professional performer, it's no wonder he's so at ease and has as much fun as his audiences. "You just sit there with a grin on your face, waiting for what's coming next," a happy client said recently.

He's appeared on dozens of TV shows, including The Tonight Show with both the late, great Johnny Carson as well as with Jay Leno, and has performed in front of more delighted audiences than he can remember, including several crowds of 20,000 or more in coliseums that rocked with laughter and cheers. His message is inspiring, motivating, and hilarious, as he relates in his relaxed, charismatic style how he's overcome such obstacles as "the sharks in show biz who stab you in the front," a stay in an African prison, and two different types of cancer.

As he says, "Falling on your face is still moving forward."
