My therapist once badmouthed a therapist we both knew (and yes, she had a reputation as a real harpy) but he quickly apologized and said that it was "unkind" for him to say anything, especially to a patient.

Hard for me to think about this without "fit issues" because I once had a brilliant therapist with a great reputation who was tempermentally wrong for me.

However, it might be helpful to know your therapist's "school of therapy". Some styles are better for some than others. Oops, sorry-a fit issue!!!
