The following classes and clubs are offered by teachers through Excelsior Classes. Please note that each shopping cart is for one student. Each student requires a separate transaction, and you will provide the student’s information at the end of the transaction.
Classes are sold individually (a la carte), and each course’s price appears on the individual class page. A non-refundable 30% deposit reserves the student’s seat in the course. The remaining tuition is subsequently billed by individual teachers and is due in August or January.
