Mental Development Coach – Professional Athletes

For more than 35 years, Dr. Jack Llewellyn has worked in the field of psychology and is considered a pioneer in the sports psychology field publishing the first book on the subject in the early 1970s.

He began to receive national recognition for his mental development coaching techniques when he was credited with turning around Atlanta Braves pitcher John Smoltz’s career in 1991. Smoltz was 2-11 halfway through the season when he began working with Dr. Jack. Thanks to the techniques he learned, Smoltz went 12-2 in the season’s second half and became one of the premier pitchers in Major League Baseball.

On the field and in the clubhouse, Dr. Jack’s subtle suggestions and ability to help players overcome challenges has made Dr. Jack a legend as a mental development coach. Teaching his players practical skills to overcome & thrive on the stress and pressure of professional-level sports has attracted professional athletes from around the world of sports.

As a professional athlete, I’m always looking for an edge—especially a mental edge—and Jack Llewellyn’s program has helped me greatly in that area. Jack’s program helped with me deal with adversity, make the necessary adjustments and recover. Jack has been a huge help with the mental side of my game.
