Two full business days notice is required when canceling an appointment. Appointments that are canceled or missed without two full days notice will be charged to you at the full fee. No future appointments will be scheduled until your fee is paid. All new evaluations scheduled on a Monday will have their credit card charged for the full appointment fee the Thursday prior to their appointment. Your appointment time is reserved for you. Dr. Stahl does not double book appointments. If you do not cancel your appointment in advance or do not show up for it, Dr. Stahl is unable to see another patient because the time slot was allotted specifically for you.
