Baseball is very much like life, it ebbs and flows with moments of intensity, moments of success and even more moments of failure.

In addition to athleticism, to be successful in baseball, athletes must have confidence, humility, emotional control, great work ethic, and the ability to support as well as trust teammates and coaches.

At Le Sandlot, we have assembled an all-star multi-disciplinary team who's purpose is to provide athletes with all of the tools necessary to be their best both on and off the field. From nutrition to strength & conditioning; from mental coaching to position specific skills coaching; from equipment fitting to physical therapy; from technical performance analysis to recruiting & communications training; our team can cover all the bases to ensure that athletes progress towards achieving their goals.

In 2018, Mash decided to follow his dream of opening a specialized baseball training facility and founded Le Sandlot so he could offer baseball and softball players of all ages and skill level a place where they can improve their game and to help players to be their very best both on and off the field.
