To cancel or reschedule, you may call us at (210) 829-3870, see us in person, or send us an email. Be ready to give your name, student ID number, and the appointment day and time. To make appointments available to other students, we ask that you give us at least two hours' notice if you need to cancel or reschedule an appointment. Any session canceled without at least two hours' notice will be counted as a no-show.
