I searched and found my own Psychiatrist. He is a ways away and didn't know my T.
They have spoken a few times. My T sends him session notes from time to time.
My PsychDoc does counsel me as well as med review. They seem to have different roles but keep the information flowing enough to provide continuity of care for me.
If I feel there is a dissconnect, I will ask them to call each other. My T hates meds.
It's interesting to have both. Basically, they are on the same page. If they weren't, I would be looking for another doctor. Good luck, you will know when you find the right one.
