As a counselor for a Failed SAP for DOT Test, you specialize in helping people who have been charged with driving under the influence. As such, you have had some of the most difficult cases to work with, and have learned a lot about what makes people tick.
This has helped you to empathize with your clients, and has led to better outcomes for them. Perhaps you would like to move beyond being a counselor for substance abusers, and instead focus on helping those who have been charged with other kinds of offenses (SAP Evaluation).
