An interventionist is a professional counselor who helps families, friends or employers of someone who is abusing drugs or alcohol and stage a confrontation with that person and persuade him to enter a treatment program. The interventionist arranges for the time and place for the confrontation. Sometimes the person involved knows in advance about the meeting, and sometimes the confrontation comes as a surprise. Before the meeting, the interventionist must also locate an appropriate treatment program based on the person’s individual needs, prepare everyone who will attend, and then put everything in place so that after the confrontation, she can be taken directly to the center and enter treatment immediately. The interventionist also works with insurance companies and employers, if necessary, to set up a payment plan for treatment and a leave of absence from work (or school), if necessary.
