Make the payment at the end of the session and set for the next appointment. It is fine if you would like to set your appointment later. We will send a reminder to follow up in a week. If you need a letter from us, you will only be able to collect it during your next visit. If it is an urgent letter, a double charge might be implied. Make the payment together with your therapy session payment and give your therapist a 10 - 20 minutes period to produce your urgent letter.
