At the end of each session, you will receive an invoice for costs to be declared to your health insurance. Different insurance companies have different refund policies, please consult the conditions of your medical plan or contact your insurance provider to see if therapy will be covered by your Dutch/International insurance, as well as how many sessions. Usually, Gestalt therapy falls under 'alternative medicine'. Please see also here.
Payment can be provided by cash at the end of each session or you can make a money transfer within 7 working days.
Cancellations can be made no later than 48 hours before the session, this is free of charge. If the cancellation is made later than 48 hours, the full costs of the session will be charged.
I am a member of NVAGT (Nederlands Vlaamse Associatie voor Gestalttherapie en Gestalttheorie) and EAGT (European Association for Gestalt Therapy), and I always work under NVAGT professional code and complaints procedure.
