“It’s like having Mr. Rogers teach your child to swim,” said one parent who left it up to The Swim Lessons Company’s Jim Reiser to show her child the secrets of not sinking. A third-generation swim teacher and coach, Jim approaches his pupils from a gentle, comforting angle that’s especially calibrated to meet the needs of infants, preschoolers, and adults disguised as Toys 'R' Us kids, employing fun activities and drills to impart skills. His friendship with water began in elementary school, and it was a friendship destined to last. To pay for college, Jim leased the university pool and used it to train young swimmers; he went on to teach aquatic courses at the University of South Carolina and lead multiple swimmers to state championships. "The Swim Professor"—a nickname Jim earned after founding Swim Lessons University, an online learning resource loaded with educational videos—now spends his days sharing the magic of swimming with people of every age, imparting the tips and tricks they'll need to survive in a pool, from holding their breath to performing a proper backstroke and catching Marco Polo.
