MEET THE DIGIULIOS
John and Kari DiGiulio have dedicated nearly 30 years to high school athletics, building a life centered around sports, mentorship, and community. Their shared passion for competition, fitness, and developing young athletes is what led them to create DiGiulio Performance—a place where athletes of all levels are encouraged to grow stronger, build confidence, and reach their full potential.
Their journey began in the spring of 2000 while teaching and coaching at La Costa Canyon High School in Carlsbad, CA, where their shared values and love for athletics first brought them together. Now married for 23 years, John and Kari have built not only a business, but a family deeply rooted in sports and teamwork. Their four children each carry that same passion—from collegiate athletics to youth sports—reflecting the environment of encouragement, discipline, and joy that defines both their home and their programs.
At the heart of DiGiulio Performance is more than training—it’s a commitment to inspiring the next generation to believe in themselves, put in the work, and enjoy the journey along the way.
