About Mackie Shilstone

America’s Premier Sports Performance Manager and Career Extension Specialist, Mackie Shilstone is one of America’s most influential fitness, wellness, and sports performance experts. His expertise has played a pivotal role in the success and longevity of a multitude of world-class athletes and celebrities.

More than 3,000 professional athletes and teams over the past 43 years have turned to Mackie for performance enhancement and wellness guidance.

In addition to working with Serena Williams, Mackie has helped two-time Superbowl-winning quarterback Peyton Manning, Hall of Fame NFL kicker Morten Anderson, and boxing greats – including World Light-Heavyweight & Heavyweight Champion Michael Spinks, World Heavyweight Champion Riddick Bowe, World Light-Heavyweight Champion Andre Ward, Bernard Hopkins and World Light-Heavyweight and Heavy-weight Champion Roy Jones, Jr – along with champions in all pro sports.

Mackie’s professional team consults have included: New Orleans Saints, Detroit Lions, Minnesota Vikings, Minnesota Timber Wolves, Indiana Pacers, Washington Bullets, New Orleans Hornets, St. Louis Blues Hockey Team, New Orleans Brass Hockey Organization, San Francisco Giants, New York Yankees, Baltimore Orioles, to name a few.

As a result of his work with Spinks on his historic 1985 win against Heavyweight Champion Larry Holmes, KO Magazine voted Mackie among the top 50 most influential people in the history of boxing. 2002 Baseball Hall-of-Famer Ozzie Smith credited Mackie in his induction speech, as he felt the partnership earned him an additional 11 outstanding years, after the age of 30.

Mackie’s celebrity clientele has included: Broadway actress Jennifer Holiday, along with actors Wendell Pierce and John Goodman – transforming 63-year old Terminator 1&2 star Linda Hamilton’s body and performance to a level not seen before in Hollywood for her role of Sarah Connor in the 2019 Terminator Dark Fate movie, at the request of Hollywood creator, producer, and director James Cameron.

While countless professionals – athletes, actors, law enforcement, and special forces – have received career-extending help from the health and fitness guru, Mackie has also transformed the lives of hundreds of non-athletes struggling with health and weight problems, poor nutrition, and a lack of motivation in his hospital-affiliated wellness programs.
