I wanted to update my posting.   Not only was I able to arrange 1:1 time for my son so that he could get some extra coaching, but the owner wrote to me to assure me that they are expanding the facility in order to accomodate the large classes.   In a world where customer service is lacking, I have to give kudos to Lees ATA Marital Arts for their attention to the parents and students satisfaction with their program.   They've been arround for 25 years and I'm guessing this is the secret to their success.   Thanks.
