My son saw a T after his father died (he was 12). A few months ago, 5 years later, he said he wanted to go back to therapy. I asked and he said he wanted to see the same person, so I arranged the first appointment and he then made his others.

My tendency is to think that if he didn't want to see the old therapist, he would have said something when you gave him the information, like "I don't want to see THAT guy" or whatever. But I think it's good to follow up and offer that you could find him the names and numbers of other potential therapists, if that is what he wanted.
