Substance Abuse Assessments are usually recommended by the Courts or Probation Officers. They are usually 1 hour in length... the length depends on your background. If it takes longer to complete the assessment there will be an additional fee.  The assessment fee must be paid in advance.  The fee is non-refundable. The appointment can be re-scheduled if needed. If you miss your appointment and do not re-schedule 24hrs in advance. You will have to pay for the appointment again. Our time is valuable...Just like yours. Upon completion, the requestor (i.e. Probation Officer,etc.) will be sent the results of the assessment.
