Book a session

Prof. of Practice (academia) and leadership capability partner (industry) to leaders across the UK, US, Europe and GCC. I help founder-led, mid-market, PE-backed companies and organisations navigate critical transitions, strengthen leadership performance and build the organisational capability to deliver strategy to execution.

This work is delivered through the Leadership Capability Operating System™ (Leader OS™) an evidence-based system for diagnosing gaps, solving problems, developing capability, implementing solutions and embedding measurable change.

For more than 25 years, I've worked with founders, executive leadership teams, private equity portfolio companies and organisations across all types of complexity and sectors strengthening leadership capability, organisational performance, accountability and strategy execution.
