TEN // International Leadership Consultancy

What our clients say about us...

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.

Bruce Bundrant, Commercial Director, AS Monaco FC

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.

Admiral Sir George Zambellas, First Sea Lord

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.

Anant Patel, Investec Structured Products

Entrepreneurs are both the present and the future. William Montgomery is doing a fantastic job getting entrepreneurs together, sharing excellence and almost literally creating the future before our eyes. I am inspired by his passion, energy and unbounded enthusiasm.

Richard Duvall, Founder of Egg and Zopa

TEN is doing a great job. The advice and support that they can offer is invaluable to any business, however large or small.

Jacqueline Gold, Executive Chair of Ann Summers
