I have worked in the Law Enforcement domain for 17 years. I started out with an operational role in UK policing, working as an intelligence and communications specialist. After several years I wanted to find a different way to make an impact; this led me to pursue a career in consulting.

I’ve worked on a range of large-scale central Law Enforcement programmes implementing new capability and legislation across the UK, and have led multiple teams implementing successful technical, business and organisational change.

What I love about working at Principle One is the opportunity to look for creative and innovative ways to support those who serve and protect the UK; it’s been a natural fit for my desire to drive positive change in UK policing. As P1's  training and development lead I am also able to help shape the careers of our junior consultants, which I find hugely rewarding.
