Meet Tom "Duffy" Dillon — a swim coach who became a Sydney Olympic coach, then an international consulting director, and now the CPO instructor students across 121 countries call when they need to be certified-ready to operate on day one.
The milestones that shaped how Duffy teaches CPO — from competitive swim coaching to Olympic duty, international consulting, and the launch of The Pool Trainers.
Began coaching at USA club and collegiate level. Built the foundation in stroke mechanics, periodization, and athlete development that informs his teaching style to this day.
Traveled the world as a head coach and aquatics consultant. Worked with national federations, club programs, and aquatic centers across multiple continents — learning the regulatory and operational variation that no domestic-only CPO instructor has seen.
Coached athletes at the 2000 Sydney Olympic Games — the largest stage in aquatic sport. Brought back a systems mindset and a respect for protocol that still shapes every class he teaches.
Served as International Director of the American Swimming Coaches Association — working with swimming federations and coaches across 6 continents. Built the cross-cultural fluency that distinguishes his CPO instruction from anyone else.
Managed aquatic facilities and coached at a U.S. Army installation in Colorado. Operated inside a military-grade compliance environment — health-department inspections, risk registers, and operational discipline applied day in and day out.
Launched The Pool Trainers as a PHTA-certified CPO instructor. Brings three decades of pool-deck, classroom, and international consulting experience into a live 2-day CPO certification students can attend from anywhere.
The Pool Trainers CPO class is built around three outcomes that map directly to what a working pool operator needs on day one after certification.
Operate balanced pool and spa water per PHTA standards — know the chemistry well enough to diagnose and correct, not just follow a log sheet.
Diagnose and resolve system issues in residential, hotel, school, and municipal pools — the operational failure mode that health departments actually flag.
Pass PHTA-aligned health-department inspections across 26+ regulated states — the same compliance lens used by municipal, school, and resort facilities nationwide.
