I am pleased with my kids improvement. I have been sending them for swimming lessons  with different instructors but did not see any improvement.  Both my kids have learned the breathing techniques, back float,  freestyle  and  how to stay stay afloat and tread water  in deep water.  They have made a lot of progress after  just 4 classes.  I have experienced many different swim instructors and classes and this one is by far the best!  I would totally recommend John to other parents.
