Frank is a great teacher, my son had over 150 classes with him and made significant progress! We really appreciated his efforts on teaching and wish my son could go further with him.

My son felt comfortable participating and really enjoyed the lesson. He thought the variety of materials was fun and helped keep the class interesting.
