Diploma in Trauma Therapy

March 2025 – January 2026 – 15 days – London

We are now accepting applications for the 2025 intake. Interviews will be in May or June 2024.

A pioneering professional training in how to work with the process of trauma in a relational way
The last six years have seen a proliferation of treatment approaches to trauma, ranging from EMDR to Energy Psychology and EFT. The danger in this is that therapeutic work gets reduced to a set of techniques rather than an integrated approach embedded in relationship. Furthermore in pursuit of ‘treatment’ the client may loose an opportunity for meaning making rooted in suffering. The intention is to support students in developing a proactive and therapeutic style, integrating different techniques instead of depending on them.

Accredited Thematic Level 7.

For whom is this training
This COSRT accredited, innovative training in working with trauma is open to counsellors, psychologists, psychotherapists or other mental health professionals. We will explore the effects trauma has on people’s development in relation to their psyche, body, relationships, work and spirituality. The course explores the mechanisms traumatised people use to organise their lives. As a specific focus we include the impact of the client’s trauma on the therapist.

The course will reflect on post-traumatic stress, single and multiple episodes of trauma, chronic trauma, accidental trauma and developmental trauma.

The overall course aims are:

  • To increase understanding of the principles and practice of a number of theoretical approaches to trauma
  • To provide practical and helpful interventions when working with clients who have experienced trauma
  • To gain a deeper understanding of the impact of trauma on people’s development in their psyche, body, relationships, work and spirituality
  • To develop a greater awareness of the contribution various theoretical approaches can make to therapeutic work with traumatised individuals and groups
  • To promote a deeper capacity to reflect on working practice and the impact of working with traumatised individuals
  • To critically examine trans-generational issues in relation to trauma
  • To critically examine the recent contributions to trauma work: neuroscience, EMDR, EFT and somatic work.

Our philosophy is Integrative, drawing on a wide range of theoretical orientations and disciplines including Trauma Focused CBT, Gestalt, Somatic and psychoanalytic thinking. It will provide a supportive and energetic setting in which learning about trauma and its aftermath can take place.

“In 2013/2014 I attended a course, the Diploma in Trauma Treatment, with NAOS. I received my Diploma recently. This brought home to me what a great experience it was, and how much completing it meant to me. Each session introduced us to a different method or perspective for working with trauma. The quality of the presenters was fantastic. I learnt so much in the year. I feel very resilient when working with trauma cases and enjoy the challenges this work brings. What I particularly love about NAOS is that they have great values, they care and in a very adult way are around to help. This year I am doing the Advanced Diploma in Couples Therapy and this too is a fabulous experience. I feel very confident to recommend NAOS.” (Testimonial provided by J Eden Riley)
