Payment is expected at time of service and can be made either by cash or check. *Reductions to the schedule of fees may be available for individuals on a limited income.
If you do not make your appointment or if you cancel with less than a 24-hour notice, you will still be required to pay for the missed session. That said, there are always allowances.
Unfortunately, sessions with a therapist are not covered by the French "Sécurité sociale." Some private health insurance plans do offer reimbursement; however, I cannot guarantee that therapy will be covered under any given insurance policy.
