What we do

Complex Trauma Institute (CTI) developed from the Complex Trauma Therapists' Network in the UK (CTTN -complextrauma.uk) and was established to support personal and professional development for practitioners who support traumatised individuals.

We know that many agencies do not offer sufficient support or training when working with trauma. Therefore, we are filling this gap by providing CPD training based on the latest research in the field of trauma, a network association that will connect you to a network of professionals working with individuals experiencing complex trauma and research opportunities in this field. 

Our Aims:

1.  to furthering information & advancing a clinical, physical, psychological and philosophical understanding of the impact of complex trauma upon individuals and society.

2. to raise awareness of effective therapeutic interventions and systemic practice: through its research, active support of front line personnel, provision of professional development & training programs.

3. to raise the standards of care for those directly impacted by complex trauma.

4. to encourage national & international collaborations via publication and conference presentation.

5. to provide electronic resources & support services.

6. to become leading pioneers in the development and practice of new and innovative Experiential Trauma recovery tools for the treatment of complex trauma. 

7. to support professionals' engagement in research projects in the field of complex trauma.

 8. to create and maintain a supportive network of professionals with a common interest through our diverse subscriptions.

9. to raise awareness and promote trauma informed therapy across Health Care Professions. 

What we offer

We offer three areas of support to achieve the aims mentioned above. Our network association includes professional and peer support, educational resources and networking opportunities. Through our experiential workshops we provide with further learning for professional and personal development. We endorse and promote research opportunities in the field of single or complex trauma.
