The therapist will take payment in full at the end of each session via cash or cheque. They do not, unfortunately, have the facilities to accept credit or debit cards on site, however you can pay via Paypal here.
You will be sent an invoice for any missed or cancelled sessions that do not abide by the cancellation agreement you have with your therapist, and invoices must be paid upon receipt. Do note that any unpaid bills may be passed on to a debt collection agency.
