You should ask for them to send you verification of their education and/or license, along with their resume. If they are hesitant or do not want to then I would question their training and expertise. You can also find out more information about them by using their name to conduct an online search or by searching professional counseling boards and/or organizations for their name. There will be some kind of legitimate reference to them online if they are trained and a true professional. If you are really stuck in your relationship, do make sure the person is trained so that they have the qualifications, skills, and techniques under their belt to truly help you.
