Seeing a T with years of experience can sometimes be counterproductive as with a supervisor. Just because you are a t or a supervisor with years of experience does not mean you are a good t or supervisor. Likewise if you are a mother and have had lots of children and experience does not mean you are good.
Supervisors should be regulated.
I read some research lately and it said that the more a t practises the less efficient they become. I will try find the link to this but I just wanted to say that therapists themselves seem to idolise supervisors and other ts who have been in the business for years without having any experience of them as therapists or supervisors.
I think clients know best what their is like and we should trust that.
