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.

Nicole Rodriguez always knew she wanted to pursue strength and conditioning, but the extent of her journey — spanning 44 countries and the Paris 2024 Olympic Games — is nothing short of inspiring. During her time at Mike Boyle Strength and Conditioning, Rodriguez recognized the value of experience and environment, later joining the EXOS International Program to coach globally. Eager to test her skills and help standardize coaching education, she sought out developing countries to advance their sport infrastructure. Rodriguez outlines key differences between U.S. and European approaches: while the U.S. excels in strength methodology, Europe enhances sport-specific application through tactical periodization. Additionally, she highlights Europe’s emphasis on rehabilitation and an “inverse relationship” between time in the weight room versus pitch-side with sport coaches. Rodriguez also describes her work with Poland’s Ministry of Sport and Tourism to pursue NSCA Global Chapter status, aligning with her passion for improving strength and conditioning education and implementation worldwide.
