Certified CrossFit Level 3 Trainer | Precision Level 1 Nutrition Coach

Born and raised in Claremont, Coach Dean has spent nearly his entire life pursuing excellence in athletics. He began competitive swimming at age 8 and went on to compete at Cornell University, where he served as co-captain of the varsity swim team, won an Ivy League Championship in the 400 Individual Medley, and finished his collegiate career ranked among the top Division I swimmers in the nation.

After discovering CrossFit in 2013, Dean quickly realized that true fitness extends far beyond sports performance. Following a successful 12-year career in consumer products and biotechnology, he left the corporate world to dedicate himself full-time to helping everyday people improve their health, confidence, and quality of life through CrossFit.

As a Certified CrossFit Level 3 Trainer and Precision Level 1 Nutrition Coach, Dean believes great coaching – not just hard workouts – is what produces lasting results. His focus is helping people at every level move better, build strength safely, prevent and reverse chronic disease, and develop the fitness needed to enjoy life for decades to come. Every class emphasizes sound movement mechanics, individualized coaching, and steady long-term progress, whether you’re walking into a gym for the first time, returning after years away, or training for the next level of sport.

Dean has also competed at a high level himself, finishing among the top 3% worldwide in the CrossFit Open. That experience allows him to effectively coach athletes pursuing competitive goals while applying the same evidence-based coaching principles that help beginners and lifelong fitness enthusiasts succeed.

CrossFit Reverb has proudly served the local community since 2012, and under Dean’s ownership since 2023, continues to deliver coaching-first CrossFit focused on helping every member become healthier, stronger, and more capable for life.

Jake earned his degree in Kinesiology from the University of La Verne while competing as a four-year collegiate baseball player. During his college career, he helped lead his team to two NCAA Super Regional appearances and gained valuable experience coaching athletes of all ages through youth teams and baseball camps. His background also includes years of competitive basketball and soccer, giving him a broad understanding of athletic development.

As a CrossFit Level 2 Trainer, Jake combines his education in human movement with a coaching style that is encouraging, patient, and focused on long-term progress. He enjoys helping beginners build confidence and develop healthy habits while also working with athletes pursuing higher levels of performance. His coaching experience includes preparing a high school football player to compete at the next level and successfully earning an appointment to the United States Military Academy at West Point.

Jake also enjoys challenging himself through events like HYROX and local CrossFit competitions, allowing him to bring firsthand experience to athletes training for competition while never losing sight of what matters most – helping everyday people become healthier, stronger, and more capable for life.

CrossFit Level 1 Trainer

With more than five years of CrossFit coaching experience, Coach Mehedi is passionate about helping people discover that fitness is for everyone.
