I strongly support interviewing the therapist without charge to ask any questions that may help you pick the right therapist before hiring her or him. You have this right . The therapist must treat you with respect and truly support your questions . Curiosity is healthy with all people especially asking questions of professionals or doctors who you are going to hire to work with you.

Questions like :
One's training, experience, personal beliefs about life, curiosity questions, personal questions, and, of course, why do they think they can help you.
