Personal Coaching for Business Leaders

Q: The Sixsess Philosophy – The Six “S”s of Great Organisations

Simple – Clarity and focus create momentum.Straightforward – Honesty, openness and directness build trust.Sustainable – The right pace and balance ensure longevity.Satisfying – Work should energise, not exhaust.Scalable – Growth must be structured and intentional.Sellable – Value comes from being transferable, not dependent.

Discreet, experienced support for founders, CEOs and senior leaders who want clarity, composure and confidence in their decisions.

Leadership can be demanding, isolating and complex.

The people who run organisations carry weight that few others truly understand.

Our coaching sessions are your space to think, talk openly and refocus perspective – with someone who’s been there.

Five decades of leading, advising and listening have taught me that people are always at the centre of what works (and what doesn’t).

This is personal coaching for those who lead businesses – discreet, thoughtful and completely focused on you.

How OUR Coaching Works

Personal Coaching for Business Leaders

A confidential, one-to-one relationship built on trust, perspective and practical wisdom.

Each engagement is private and designed around your context and pace.

Some leaders work with me for clarity before a major decision; others for ongoing counsel and balance.

Leadership Team Coaching

I also work with senior teams to help them align around shared purpose, priorities and pace.

These sessions are straightforward, human and focused on practical outcomes.

Working Together

If you lead people and carry responsibility, you deserve the same quality of support you give others.

That’s what Personal Coaching for Business Leaders is:

a trust-based relationship – space to reflect, refocus, regenerate and renew.

I have had the pleasure of working with Barry a couple of times and highly rate his experience, professionalism, and skills particularly in the field of change and transformations. Barry is exceptionally people focused and has a wealth of experience which he can apply and adapt to organizations across the globe. He has the background and skills to work with leadership teams to enable them to address the challenges faced in leading change. Barry also has the experience of working with managers and teams to help them to address the complexity of change and to build their capabilities. His background in the aviation and airline industry mean that he has experienced leading change in complex situations which provides a unique approach to Barry's focus on the people-elements of change.

I worked with Barry for many years... in a way he was my personal mentor. His achievements became the stuff of legend. Barry will bring his unique experiences to the benefit of his clients in the future. I would highly recommend any organisation that faces a need for change to contact him immediately.

It’s difficult to quantify outstanding qualities in a leader, but these are a good start when talking about Barry. His boundless enthusiasm for a task is truly infectious, and he knows just how to bring out the best in his colleagues.

I've worked with Barry as I develop and continually move forward with ULTIMAR, and his support and input has been extremely valuable. He brings clarity, structure, and a no nonsense mindset to problem solving. His support and advice has not only shaped key decisions but also made our entire process more effective and rewarding. Highly recommended.

Barry has been generous in sharing his vast knowledge, innovative tools, and insights, which have been instrumental in helping me plan ahead and navigate the complexities of launching a new venture. It’s been a true pleasure interacting with him, and I’ve gained immense value from our engagements.
