Who We Are

We bring decades of experience and deep expertise, working with a wide range of organisations with different challenges, to help you tackle your people and organisational challenges.

When clients partner with us, their challenges become our challenges.

We get curious about what makes our clients tick. We work hard to understand their context and address the right questions to work out what will make a real difference. We excel in crafting the right environment for deep thinking and decision. This enables everyone to have the right conversations to generate unique solutions that become a springboard for action.

Our story begins in 1998

Mightywaters was founded in 1998 by Mark Withers and Anna Withers. After successful and extensive senior management experience in large corporations and consulting, we wanted to offer clients a more personalised approach to consulting that put their needs and ambitions firmly at the heart of our work.

Our values are the heartbeat of how we work. We are contemporary, act with integrity and are responsive and agile. We are curious and invest time understanding the problem so that we can act with purpose. If we commit to something we always deliver it.

We are proud that so much of our success has come from people we have worked with time and again and who recommend us to others. We believe it’s a great testimony to the quality of our work and the way it is delivered. We never take this for granted yet, after a quarter of century, we are confident that building enduring client relationships really matters.
