I personally think it's best to find a therapist that either specializes in trauma or at least has experience with it.My T not only specializes but also has over 30 years of experience.
He tried whatever he thought would help me most.Since my traumas varied so much,so many different types of abuse and trauma,for some it was DBT,some CBT,some ACT(acceptance and committment theray) and everything else in between,even EMDR for one specific trauma.
I was happy he changed things up by what he felt was needed.
