There is a $100 program deposit required to hold your date/time. Deposits are non-refundable (except in emergencies or cancelations by SERC staff) and go towards your total program fee. Once you tentatively book your program with SERC Education staff you have 10 business days to pay the program deposit or your date/time will be freed up for other groups. You may pay by cash, credit card, or check. Call 443-482-2216 to pay by credit card.
