Therapy is a process, not an event.  This means that therapy is not just important when you are conscious that meaningful things are happening.  Every session is important, even if you are not aware of it.  Consequently, we require that you attend every session agreed to in your plan, except where extenuating circumstances such as illness are affecting your schedule.  If you cannot attend, notice should be given at least 24 hours ahead of the session.  My schedule remains full.  Consequently, if you do not provide notice of your absence, someone else may not be able to use the time.
