As a parent, you have likely had dozens of teachers as you worked your way through schooling. You were probably taught history, math, English, and other subjects with a handful of other instructors. Each teacher had something new to offer you –new information, new energy, new rules, and this was a completely normal part of your schooling experience. Some teachers you loved, some weren't quite your favorite, but all contributed to the knowledge you have today. Swim lessons are very similar and there are many perks in swim instructor turnover.
