Michael Phelps wanna-bes are in the right place to perfect their strokes. This swimming school was founded by Olympian Casey Barrett and former NCAA champ Lars Merseburg, and recently counted 2010 Olympian Anthony Ervin as one of its teachers. Kids as young as six months splash around alongside parents in the Imagine Starfish class, eventually picking up water safety tips and stroke skills in subsequent classes before learning competitive strokes in Imagine Dolphins. More advanced students can join the Manhattan Makos swim team. Note there are various locations. Ages 6 months and up.
