Prior to founding Warren Larkin Associates in 2017, Warren spent 25 years in the NHS, working predominantly with individuals and families experiencing serious mental health difficulties.

Working first as an assistant working on the long-stay psychiatric wards at Prestwich Hospital, and then as Clinical Psychologist in Manchester in a service created to provide and research the impact of CBT and Family Interventions for people experiencing psychosis.

Warren went on to lead one of the two national centres of excellence in psychological care for psychosis – chosen to share and disseminate innovative practice in first episode psychosis services (FEP). This initiative contributed to a case for change which led to increased funding, and the introduction of the two-week referral to treatment time in FEP services in England.

Warren then spent 5 years as Network Clinical Director, responsible for Children and Families Services across Lancashire. Warren was responsible for the quality and safety of care and for research and innovation. This experience led to Warren's passion for public health and prevention work.

Warren is a Consultant Clinical Psychologist and in addition to his clinical work with people experiencing psychosis and trauma, he has remained an active lecturer and researcher holding many honorary academic positions, including 6 years as Visiting Professor at the University of Sunderland.

He has a long-standing interest in the relationships between childhood adversity and outcomes later in life and has published numerous research articles on the topics of adverse childhood experiences and trauma and psychosis, and published an edited book in 2006 exploring this theme.

Warren completed a 2-year tenure as the Clinical Lead for the Department of Health Adverse Childhood Experiences programme, and has also worked with the Scottish Government and NHS Health Scotland to implement routine ACE enquiry in GP practices in some of the most deprived areas in Scotland.

Warren developed the routine enquiry about adversity in childhood (REACh) approach as a way of assisting organisations to become more trauma-informed and to train professionals to ask routinely about adversity in their everyday practice.

Warren has also been involved in policy development and has acted as an advisor to a number of UK and foreign government agencies. He was a member of the Children and Young People's Mental Health Services National Task Force, the NICE expert reference group on first episode psychosis, the 'Tackling Child Sexual Exploitation' advisory group and was a contributing author of the Personality 'Disorder' Consensus Statement. He has also been supporting UNICEF in the Western Balkans to develop trauma-informed policy and practice.

Warren recently led the implementation of trauma informed approaches as part of a randomised controlled trial in 100 secondary schools in England, which was evaluated by the Anna Freud Centre and funded by the Youth Endowment Fund and the Home Office.

Having left school with one O'level and one CSE, very low expectations, and what turns out were the prerequisites for intractable imposter syndrome, he feels strongly about applying trauma sensitive and relational approaches to educational settings.

Warren and his colleagues work extensively across multi agency settings, providing consultation, training and supervision to clinicians, practitioners and leaders on trauma and psychologically informed practice, interpersonal skills and avoiding burnout.
