What don't I love? We have done other swim lessons other places and I just have never seen this much progress this fast. That is one big difference I have noticed. But that aside, I love how the teachers show you how they are progressing at the end of the lesson and seem so genuinely interested in the kids going forward. They have always seemed to love what they are doing and not simply "doing their job." I also love just all the excitement along the way from encouraging them with little bits of candy and ribbons when they progress to high fives after class. My kids LOVE going to lessons and it has never ever been a battle. They do a fabulous job and I would highly recommend it to anyone looking !
