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.

Sam Moore’s path into sport science is defined by taking risks and chasing meaningful questions. After a devastating knee injury as a collegiate athlete, Moore not only returned to compete, but she also discovered her calling in strength and conditioning. She recounts her coaching, sport science, and hybrid roles prior to leaving a full-time position to pursue her PhD at the University of North Carolina at Chapel Hill. Moore describes sport science as problem-solving and drawing evidence across disciplines to drive innovation. She discusses her research on female athlete availability in elite settings, including nuances like body composition, recovery, and high speed exposure in training. Moore advises young professionals to remain open-minded, pitch their ideal position if it does not exist, and go “all in”— knowing one decision does not define forever. Whether you are a coach or researcher, this episode delivers real-world insights on navigating your career with courage and curiosity.
