2022-2023 Session

Session Dates: 9/6/2023-6/22/2024

This fall-spring session, following the Public Schools calendar. We are open on all small public holidays for regular class schedule, and we also offer minicamps on those days. We are closed for one week for school vacations in December, February and April. In general, due to the high volume of children we serve, we do not offer free trials. To hold your spot in class, your first month’s tuition and the registration fee are due when you register. After your first class, you can request a full refund if you think we are not a good fit for you. If you choose to continue, you will be enrolled in auto-pay and your credit card will be charged your monthly tuition on the 1st of every month up to June 1st of every year. To leave our program, please give us written notice before your last month of classes. See policy details on our Policies page.
