Schedule Changes
Class cancelation and schedule changes are driven primarily by your attendance. Classes with low and/or inconsistent attendance may be canceled for the upcoming session (Winter/Spring/Summer/Fall).  If you enjoy a particular class in a specific time slot, do your best to make it in as often as possible. Sustained attendance and continual participation are necessary to make the class viable for our marvelous instructors and for a family run small business. The teachers may also have the opportunity to offer a different format in which they are trained in an effort to increase attendance before the time slot is canceled. Show your favorite teachers your support! We'll see you in class!
