Tom Williams’ journey to Head of Performance and Sport Science for Major League Soccer (MLS) powerhouse, the Los Angeles (LA) Galaxy, began at a crossroads: pursue traditional coaching or medical pathways. As a soccer “Swiss Army knife,” he embraced early sport science alongside coaching, building a career defined by collaboration and innovation. At the Galaxy, Williams is part of a web of support that uses rich data storytelling tailored to stakeholders and players, guiding decisions and infusing value in every encounter. This system drives their three key pillars: winning championships — including their recent record-breaking sixth MLS Cup — developing a robust academy pipeline, and leading innovation. In MLS’s “cultural melting pot,” Williams balances diverse backgrounds and short-term demands like fixture congestion while employing sustainable long-term strategies. With a unique full-time cognitive department and creative approaches like dodgeball warm-ups, he combines trust and ingenuity to elevate performance and presents a blueprint for those exploring emerging sport science.

Lanier Coleman coaches from a simple truth: intent drives intensity. Now in his role as Assistant Strength and Conditioning Coach for the National Football League (NFL) Jacksonville Jaguars, Coleman brings the same determination he embodied as a collegiate defensive lineman. He shares how early adversity shaped his standards, teaching him to lead with discipline, cultivate deeper relationships, and “build a fire” in every athlete he coaches. During his coaching tenure at Florida State University, mental and emotional endurance became cornerstones of team development — these are lessons he now carries into professional football. Coleman describes the shift from building collegiate foundations to coaching with precision at the NFL level, where he fine-tunes elite qualities to manage injury risk. He also stresses the importance of unified performance staffs to support athletes through this fast-paced and demanding sport. Gain inspiration to strengthen daily purpose, be a spark in your facility, and support athlete readiness across high-performance environments.
