Murray is a clinical and sport performance psychologist who first introduced the concept of scoring the mental side of a sport in developing the MPI or "Mental Performance Index" for American football. He is also the author of the best-seller "Smart Tennis: How to Play and Win the Mental Game" (Jossey-Bass/John Wiley, 1999) endorsed by World Number One Lindsay Davenport.

American tennis professional Vincent Spadea wrote and talked about the mental coaching he received from Dr. Murray as a major factor in helping him overrcome the longest losing streak in tennis history, 21 straight losses. He would return from #229 to #18 in the world, winning his first tournament in Arizona in 2004, and defeating Andy Roddick and James Blake along the way.
