Without knowing anything about the specific books or beliefs of this T it is hard to assess whether these are "red flags" or not. I am personally very skeptical of Ts who suggest clients have repressed memories-- but I don't know anything about this particular T's work so I don't feel like I can comment on that. However, if YOU are worried about this particular T, why not ask your current T for a second recommendation? I'm sure if she is able to come up with one name, she can come up with a second one also. You can either tell your current T your concerns, or you can simply say you want 2 names so that you can decide on who you feel most comfortable with. I think that's a totally reasonable request.
