Oliver James recommends Hoffman
Therapy should enable you to gain a true understanding of the ways in which the care your parents provided in early childhood are corrupting your relationships and capacity to fulfil yourself. But it all too rarely does this.
Cognitive Behavioural varieties (CBT) actively discourage dwelling on the past. While psychoanalysis, or therapies deriving from it, ought to do that job, too many analysts over-concentrate on the patient's relationship to them.
In making referrals, I often suggest something called the Hoffman Process rather than these. It is the most systematic method I know for properly exploring the role of childhood as well as offering a motorway back from the past.
