'3DTA ' stands for 3 dimensional Transactional Analysis and comes from the DVD I developed in 2005 as an Introduction to the concepts of TA. It seemed a natural progression to name the Training Institute after it. The aim of 'The 3DTA Institute' was to provide the 3 dimensions of Clinical TA; Training, Supervision and Therapy in a warm welcoming environment. This has now extended to include Mindfulness training... The '3DTA Training and Mindfulness Institute'.
