Jo Clarke PhD, C.Psychol., AFBPsS, EuroPsy HCPC Registered Forensic Psychologist

Founder and Director

During 23 years of working in the criminal justice system, Jo’s attention has focused on the concept of resilience, both for individuals and the organizations in which they live and, or, work.

For criminal justice staff, questions about surviving and thriving in roles that often involve exposure to potential trauma led Jo to undertake a PhD in the area. Since its completion in 2004, she has worked with a wide variety of organizations and individuals applying research evidence to practice, to enhance psychological well-being.

In 2003, Jo became accredited to deliver The Challenge of Change resilience training; an evidence-based intervention developed by Dr. Derek Roger of the Work Skills Centre. Jo is a regular speaker, both nationally and internationally on the subject of individual and organizational resilience and has authored a number of chapters and papers on the subject.

Since 2013, Jo has been working with challenging and disruptive children. Training with Dr. Ross Greene www.livesinthebalance.org in the application of The Collaborative and Proactive Solutions (CPS) model, Jo is committed to finding ways of enhancing the resilience skills so often lacking in such children, whilst also supporting parents, carers and professionals charged with their care. Jo is the first person in the UK accredited to deliver the one-day CPS programme. Jo is also currently an external examiner for the MSc in Forensic Psychology and Mental Health at Queen Mary’s University, London.

A mum of a now adult daughter and foster carer of teenagers, Jo also has a menagerie of animals, including a registered therapy dog and two horses in training to assist in interventions with children.

Ed Simpson - Petros People

Ed Simpson

Ed joined the Police Service in 1995, initially working for West Yorkshire Police in his hometown of Bradford, before transferring to North Yorkshire Police in 2003. Ed then remained at North Yorkshire Police until his retirement in 2016 on medical grounds, following a prolonged battle with Post Traumatic Stress Disorder (PTSD) and depression.

During his service Ed was well known for his caring and compassionate policing style, maintaining a victim focus and, through his work as a dedicated Neighbourhood Police Officer, always striving to bring local communities together.

Ed was also a Police Family Liaison Officer working with families whose loved ones had died as a result of road traffic Collisions, murder or manslaughter. It was dealing with one particular family’s grief that Ed developed PTSD. However, it wasn’t until four years later, in 2012, while Ed was working as a Custody Sergeant in York, that this developed into a severe episode of depression that almost cost him his life.

On return to work Ed took the decision to be open with colleagues about why he had been absent (not something spoken about in the emergency services at that time). He expected to be the only sufferer, but he found quite the opposite to be true.

Ed now speaks about his career experience to audiences all over the country, working closely with the national mental health charity MIND on their Blue Light program, aimed at raising awareness and challenging the stigma of mental health illness within the emergency services. Despite his eventual medical retirement, after 21 years’ experience as a Police Officer, Ed continues to tell his story to public and private organisations, to educate, inform and inspire. 

Importantly, Ed is also a stay-at-home-dad with two school-aged children, both of whom love to provide him with plenty of new daily challenges.
