If you need to reschedule your appointment, please do so at least 24 hours before your appointment is scheduled to begin. Otherwise, you will have to purchase another session (or one of your package sessions will be deducted).
I abide by this standard 24-hour cancellation policy as well. In the rare case that I need to cancel your appointment or reschedule you less than 24 hours before your scheduled appointment time, you will be rescheduled for the session you purchased, and you will receive an additional session for your inconvenience.
Please make sure you're comfortable with this mutually-beneficial policy being applied without leniency before you purchase a session or package of private sessions.
