Scaling People, Powering Growth

If your business is looking to grow, restructure, or improve workforce performance, I can help you build and execute the right people strategy—tailored, agile, and results-driven. Whether you’re expanding, integrating teams, or navigating complex challenges, I bring the insight and hands-on experience to deliver lasting impact.

With a wealth of experience in senior HR leadership roles within fast-paced, complex environments, I have a strong track record of driving people strategy and operational excellence at scale.

At Mitie, I served in progressively senior HR roles over three years, culminating in my position as Head of HR. In this capacity, I led the People function supporting over 35,000 employees across four diverse business divisions: Clean Environments, Security, Integrated Facilities, and Engineering. I was responsible for developing and executing the overarching People Plan in alignment with strategic business goals, partnering closely with the Managing Director and senior leadership to deliver commercially focused, outcome-driven HR solutions.

Prior to this, as Lead HR Business Partner, I led a UK-wide team of six regional HR Business Partners, delivering comprehensive HR services across three divisions and managing the people agenda for 20,000 employees across London and the South. I provided strategic leadership, workforce planning, and guidance on complex employee relations issues, organisational change, and performance management.

Earlier, as Regional HR Manager, I oversaw HR operations for 5,000 employees within Mitie’s Transport and Manufacturing sectors, where I was instrumental in supporting restructuring, talent development, and the implementation of consistent HR practices.

This extensive regional HR leadership experience-delivered in a high-volume, multi-site, and fast-paced environment, has equipped me with the agility, commercial acumen, and strategic foresight to support other businesses in navigating complexity, scaling their operations, and building resilient, high-performing workforces.


If your business is looking to grow, restructure, or improve workforce performance, I can help you build and execute the right people strategy – tailored, agile, and results-driven. Whether you’re expanding, integrating teams, or navigating complex challenges, I bring the insight and hands-on experience to deliver lasting impact.

“Why would we need a consultant? We’ve already got HR.”
It’s a question I hear often – and honestly, it’s a fair one.
But the reality is, most in-house HR teams are already at full capacity, focused on keeping operations running, not driving strategic change – that’s where I come in.
