Jon worked in hostels for homeless people for ten years before qualifying in 1996 as a mental health nurse in Bradford. He went on to work in mental health intensive care at the Maudsley before returning to the homelessness sector as a clinician. He co-wrote two chapters of Professor Phil Barker’s Psychiatric and Mental Health Nursing (Arnold 2004) about applying the assertive outreach approach to the care of homeless people. From 2002, Jon headed up the mental health investigation team for the Health Service Ombudsman and then led Guy’s and St Thomas’ nationally recognised complaints and legal team. In 2008 he took the position of Ethical Standards Officer at Standards for England, leading a team responsible for conducting investigations into allegations against local government members.
In 2011, Jon and Alex established ch&i associates. Since then, Jon has also undertaken independent investigations for a wide range of organisations, including into homicides by patients of mental health services, the conduct of local government councillors, and for the Parliamentary and Health Service Ombudsman, Ofqual and a Clinical Commissioning Group. Jon was also brought in as a specialist interviewer / investigator by Dr Suzanne Shale, who led a team reviewing workplace culture at Save the Children UK following reports of misconduct by senior managers there (and in light of the way those reports were handled by the charity). Most recently, Jon has been conducting independent investigations into complaints of bullying and sexual misconduct within UK Parliament.
In 2013, Jon was appointed as the Independent Complaints Assessor for the Department for Transport, adjudicating in final stage complaints against the executive agencies of the DfT (including the DVLA, HS2 & DVSA). Jon has also served as an Independent Complaint Reviewer for the Charity Commission (2011-2013), The General Medical Council (2018-2021), The Public Services Ombudsman for Wales (2018-2021), the Fundraising Regulator (2017-present) and the National Archives (2018-present)
