This month's Terrific Teacher is one of the best swim instructors in the Valley. While young, as a college sophomore, John Coughlin teaches hundreds of kids to swim during the summer months. One mom is especially appreciative of Coughlin's ability to help her daughter overcome her fear of the water. Coughlin says he's been teaching for four years and has plenty of games to keep things exciting. He also talks about the challenges of getting cranky or scared kids in the pool and having fun. Hilary Golston has the story.
