Raffinée Wilson, M.S., LPC
I'm speaking from the perspective of a mental health therapist. One of the most important traits I believe is needed is authenticity. Clients engage in therapy and are looking for a safe space. It's so important that a therapist is genuine, honest, and real in their presentation to the clients. It's usually one of the things that leads to clients staying or leaving. Outside of that, I would say being competent and trustworthy. Sad to say, there are some incompetent professionals out there. The incompetence may not be across the board, it may be with certain areas and that is to be expected. In knowing your limitations, you will be able to refer out when necessary. Also, there's a lot you learn in school and even more on-the-job training that happens when you begin meeting clients.
