Bruce Bundrant, Commercial Director, AS Monaco FC

I was fortunate enough to spend a year with William Montgomery enhancing my leadership skills and competencies through his 10/10 programme.  He's an exceptional motivator and teacher, and truly inspires you to think differently.

Admiral Sir George Zambellas, First Sea Lord

William Montgomery's style - self effacing, intriguing, imaginative, but with a clear authority - is a great fit for very many of today's leadership needs and the development of skills. I have worked with him to support a wide diversity of leadership challenges, and his focussed response and flexibility is impressive and valuable.

Anant Patel, Investec Structured Products

The facilitation to help our leadership team develop a strategic plan for the business was truly inspirational. The result is an invaluable roadmap for the future.
