About US
Our Story
Ostling Training was founded in 2001 by Mark Ostling, a former Probation Officer and Staff Development Officer with more than a decade of frontline experience. Since then, we have worked with HM Prison and Probation Service, the Probation Institute, and international organisations, delivering transformative programmes in high-pressure environments.
Our training transforms how professionals approach challenges, build resilience, and empower the people they work with.
What We Do
Criminal Justice Sector
We design and deliver training for probation services, prisons, and voluntary agencies. Programmes focus on motivational interviewing, pro-social modelling, groupwork skills, and managing risk — equipping staff with evidence-based tools for safer, more effective outcomes.
Private Sector
By applying the same proven principles in new contexts, we help businesses resolve conflict, improve communication, and support personal and professional growth. From law firms to large corporates, our tailor-made programmes strengthen workplace culture and productivity.
