I took a roll class from Kelly. I have had some previous instruction in rolling and in boat handling techniques, but I learned more from Kelly in three hours in the pool than I did in a two day course from another instructor. I am very close to being able to roll after only one class. I'm sure with another class I'll be able to roll quite well. Kelly has a unique capability to explain how to roll, and has the patience to work with people who are having difficulty learning. He is a great teacher!
