I am also a rather difficult client and it shows in the therapy relationship. I have worked with my current T for nearly 5 years, and have worked with an adjunct T on three occasions. The first was recommended by my primary T and he referred me to her. At the time, I was getting triggered by my own T and his resemblance to my abuser, but was also deeply attached to my T and really wanted the corrective experience of working through things with him. The T he referred me to was a young woman and mostly I spent my sessions with her processing my reactions to my primary T. I worked with both of them weekly for about 6 months and had signed ROIs so they could coordinate care. It helped bring stability to my primary therapy relationship.

The second time, I had hit a rough patch with my primary T again, we were stuck in re-enactments, and like EM, I felt mildly (or perhaps even moderately) gaslit at times when his version of what went on in the room didn't match mine, and he tended to think he had a firmer grasp on reality than I did. That time, I worked with a therapist in his practice who actually reported into my T. This therapist was a young, male, amazingly talented doctoral student who didn't let the fact that my T was his boss influence him. I did a lot of reality checking with him, and we talked a lot about power, privilege, and gender. He would tell me, "Don't let him dictate reality. Get back in there and fight for your right to exist!" I worked with him, alongside my T, for about 6 months and it was very helpful.

The third time, I was going through a stressful work situation and was having a lot of somatic symptoms. I sought an adjunct female therapist who could do somatic work with me and who also specialized in the intersection of personal, historical, and social trauma (and all of the "isms"), which were relevant to my work situation. I worked with her for about two months and it was also helpful. I was working on different things with her, so she and my primary T didn't coordinate care, although they knew about each other.

I do not have much respect for Ts who have a blanket policy of refusing to work with a client who is working with another T. I think it can be extremely beneficial in certain circumstances to have more than one T.
