Frank Pia’s influence is still seen today in lifeguard training and best practices at countless pools and beaches. An experienced lifeguard and educator, Larchmont, N.Y.-based Pia opened people’s eyes to what drowning truly looks like and how it could be missed by overworked or poorly trained guards.

With those principles in mind, he's spent countless hours developing practices and curriculum with the Red Cross, the world's largest lifeguard training group with 300,000 people enrolled last year in its programs.

He also brought his science-based approach to the CDC’s Model Aquatic Health Code, where he served on the subcommittee on bather supervision.
