In his role, he is a resource to Major League players and staff, is involved in player development at each level in the minor leagues, and he assists the scouting department with psychological evaluations of potential draft selections.

Geoff joined the Phillies after a fifteen-year career (2001-2016) as a founding partner at Winning Mind, LLC, a San Diego-based consulting firm specializing in performance under pressure and working in corporate, sport, and military environments.

In 2016, he published a Spanish translation of Intangibles, making it the first baseball psychology book to be published in Spanish.

In addition to his work in Major League Baseball, Geoff was a resource to player agents and amateur athletes in all sports as well as to corporations. He has consulted with such corporate clients as Pandora, MetLife, Chick-fil-A, and Genesys. He has lectured to a diverse mix of audiences, including Leaders in Sport, the SABR Analytics Conference, the American Baseball Coaches Association, the Golf Coaches Association of America, and the USMC Wounded Warrior Regiment. He has led intensive academic skills training programs for NCAA football players, headed up golf psychology duties at Okemo Valley Golf Academy in Ludlow, VT, and has developed programs for retired athletes transitioning into new careers as well as for teaching young athletes how to become role models in their communities.
