About Us
Where this all started.
Athletes spend years learning what many never have the privilege to learn. We believe sport shapes character, builds community, and opens doors that nothing else can. That's why we started Ripple Affect.
Our Mission
The Ripple Affect Foundation exists to turn the passion of athletes into positive action — creating ripple effects that expand access, inspire leadership, and strengthen the future of sport.
The Team
The people doing
the work.
Yaseen El‑Demerdash
Founder and President
Yaseen started swimming competitively at the age of 7. In high school he started to discover his true appreciation for the sport and all it had to offer. By the time he graduated high school, he was a national team rostered athlete, American record holder, and an 8x All American. Following his graduation, he went on to represent the United States at the 2023 Para Pan American Games. Yaseen came home with 4 medals , including gold in the 100 backstroke. The following year he was named to his first Paralympic team, and represented the United States at the 2024 Paralympic Games in Paris. Inspired by all the lessons and amazing connections he made during his time training and competing for Paris, he founded The Ripple Affect Foundation in 2025.
Jack O'Neil
Vice President
Jack had his leg amputated at 9 years old but found freedom in the water. That freedom led him to become a Team USA Paralympian and three time Para Pan-American Games silver medalist. He became the first athlete with a disability to qualify for state swim meets under able-bodied standards in Illinois and Colorado, and went on to represent the United States at the 2024 Paralympic Games in Paris. Now retired from sport, Jack works in sports broadcasting and as a professional speaker.
Darren Mallot
Treasurer
Darren began swimming at 7 years old with his local club team before continuing through high school competition. During the pandemic, he transitioned to cross country and track, where he quickly found the same sense of discipline and community that originally drew him to swimming. He earned multiple state-level finishes across both sports before stepping away from competition after high school.
Since then, Darren has completed the Los Angeles Marathon and recently moved to San Francisco to begin his career in wealth management. Outside of work, he enjoys live music, fitness, travel, and exploring new cities.
