Coach Alison Mattias – Assistant Coach

 At a young age, I was encouraged to start running by a friend on my swim team who made me run a local 5k with her. It wasn’t long before I fell in love with the exhilaration that running can bring. I started racing with a club team in middle school that prepared me for the training at Foothill High School. Enduring the long runs and early morning practices in high school strengthened my bond with my teammates and made me a stronger athlete and individual.

I was fortunate to continue this journey for the University of San Diego where I solidified my interest in long-distance races. Post-graduation, I continue to run every day, and I am hoping to run more marathons! The opportunity to coach has enabled me to share what I have learned from the mental and physical challenges of the sport over the years. I am grateful for the chance to run alongside the Yorba Linda athletes and motivate them to achieve their running aspirations.

Coach Jonathan Sheatz – Assistant Coach

At a young age, I participated in various sports with my younger brothers from karate and soccer, to swim and golf.  As much as I enjoyed golf and swim, I was never really inspired to consistently practice.  Running did not become a part of my life until my 8th grade year at Tuffree Middle School.  After running the mile each week I realized I was gradually improving my times.  My PE teacher that year strongly encouraged me to consider cross country and track when I got to El Dorado.  I started cross country camp the summer of my Freshman year and never considered another sport.  

I competed in cross country and track all four years in high school, and two additional years at Fullerton College.  I began my coaching career starting at Fullerton College and continued while I was working on my bachelor’s degree at Cal State University of Fullerton .  Throughout this journey, the coaches that left an indelible impression on me were the ones with the sincere belief that I could always get better if I believed in the process.  Regardless of an athlete’s ability or experience level, there are always a way to improve.  That mantra and positive belief in what is possible are things I hope to share with the athletes I have an opportunity to coach.

Coach Caesar Gallardo – Assistant Coach

I am an avid hiker, camper, yogi, and rock climber. I have been part of the running community my entire life; from my mother bringing me on runs in a stroller, to competing in countless cross-country and track races. Running has been an insane adventure that has brought me experiences I wouldn’t trade for the world. I have met the greatest people through running, whether they became friends, or were simple one-time conversations. I am excited to be part of the Yorba Linda High School Cross Country coaching staff. I hope to watch and help these young runners grow as amazing athletes and outstanding people.
