Professional is probably most accurate. He's my doctor and my therapist, and he upholds a really high degree of professionalism. Our relationship is oddly both more and less formal than the one I have with my other healthcare providers--my therapist and I don't chat about our lives the way my PCP and I do, and my therapist's emails are extremely formal compared to the ones my other doctors and I exchange, but my therapist is the one who's seen me cry, who's shared how he feels about some of the most difficult things in my life, and who laughs easily and often when we talk. It's different, but clearly in the same category for me as other healthcare providers.
