Sergio Trejo holds a Bachelor of Science in Developmental Psychology from Saint Mary’s College of California (2009) and a Master’s degree in Clinical Psychology from the University of San Francisco (2011). He is a licensed Marriage and Family Therapist (LMFT) with a deep-rooted passion for both athletic performance and mental wellness.
Sergio’s connection to sports psychology began in high school through the San Francisco Parks and Recreation Youth Golf Program, where he served as an Assistant Instructor. His early involvement focused on helping youth develop foundational golf skills and confidence on the course. This formative experience sparked a lifelong interest in the intersection of psychological development and athletic performance.
While pursuing his undergraduate degree, Sergio emphasized youth neurodevelopment, which further informed his approach to working with young athletes. During his graduate studies, he returned to the SF Park and Rec Youth Golf Program as Lead Instructor, balancing academic pursuits with hands-on instruction and mentorship.
Following his formal education, Sergio entered the mental health field, gaining licensure as an LMFT and working extensively with individuals and families across the greater Bay Area. His clinical work is informed by a deep understanding of developmental processes, emotional resilience, and mental conditioning.
In 2013, Sergio expanded his focus by immersing himself in Brazilian jiu-jitsu (BJJ), becoming a dedicated practitioner and eventually a competition coach. With over a decade of BJJ experience, he now specializes in helping athletes prepare mentally and physically for high-level tournaments. His coaching style integrates performance psychology, somatic awareness, and mindfulness practices to help competitors perform under pressure.
Today, Sergio seeks to bridge his diverse background in golf, martial arts, and psychotherapy to support athletes in developing greater self-awareness, mental clarity, and focus—both in and out of competition. His holistic approach aims to foster not only peak performance but also long-term personal growth and resilience.
