It is true, zooropa.

What you quoted doesn't mean the patient can have more than one individual therapist. It means the patient can have other professionals treating them in other capacities. For instance, I have had other professionals as part of my treatment team who were also therapists, but their job wasn't to do ind. therapy with me. Like I had my ind. therapist, plus I has my DBT instructor therapist, plus I had my vocational therapists...all professionals and trained in DBT. They had different roles. But I wouldn't be surprised at all if your T doesn't follow DBT protocol since she never has before.
