ilisten, can you ask your therapist more about the colleagues he has recommended and who he thinks would be a good fit for you? He probably knows all 4 of them and also gets reports back from clients he has referred to these pdocs before. So he hears client feedback, both good and bad. He also knows you really well and probably has a sense who would fit well with your personality. I think having a list of 4 as a starting place is a good place to be in, and easier than trying to find a pdoc randomly from the phone book, for example.

Your therapist and pdoc need to have a relationship of mutual respect. There may not be much communication between them at all, or there may be quite a bit, if it would be helpful. (You will need to give them permission to speak with each other if they would like to.) I go to a PNP who was recommended by my therapist, and he told me quite a bit about her beforehand so I had a good sense of why my T was recommending her, her expertise and philosophy, etc. Also, when I needed a referral to a family therapist, my T gave me a list of 6 names and we went through them together one by one, with T telling me what each was like, their personalities and specialities, etc. It was so helpful. Your T can be a great resource in helping you choose.

Good luck.
