The Story of TCM

The TCM Group was formed in 2001. Since that time, we have become an award-winning and well regarded leader in the fields of transformational culture, resolution, human resources, conflict management, employee relations and leadership development. With a global team of world class consultants, we have offices in the UK and the US and we operate across the globe.

Accessible and Practical.

In the past, engaging management consultants often meant wading through complex jargon and unfathomable concepts and frameworks. Not any more. TCM offers a modern and accessible approach to management consultancy. Our programmes and assignments are delivered in a which is straight-forward and practical. For a no-nonsense conversation about culture, leadership or resolution, please contact us now.

The TCM Experience

We empower people and organisations to adopt purpose-led, person-centred and values-based approaches to culture change, conflict and complaints resolution, human resources, people management and leadership.

We are passionate about protecting relationships whilst securing lasting and sustainable outcomes at times of conflict, change, crisis, controversy and challenge. We work in partnership with our customers to develop the overarching strategies, core values, systems, process, mindsets and behaviours which engender a fair, just, inclusive, sustainable and high-performing culture – a transformational culture.

Our Purpose is Putting People First

What we do

Our customers benefit from our insightful teaching and consultancy methods which are accessible to all. We are inspired by approaches such as behavioural science, positive psychology, appreciative inquiry, restorative justice, principled negotiation, nonviolent communication and emotional intelligence.

We believe in the ability of people to resolve often intractable problems with compassion and collaboration – when the correct conditions are in place. We also believe that an engaging, empowering and proactive resolution of business challenges is more effective than the confrontational, adversarial and often punitive approaches which are currently in use in a great many organisations.

“I love being a co-ordinator at TCM because I am given access to so many different learning opportunities. The support to learn new things is unlike anything I have experienced previously. And this is just one part of a continuous learning and creative work environment that I get to enjoy.”  – Rebecca Mackinnon, people and culture systems coordinator.

Transforming cultures since 2001

Our CEO David Liddle’s second book, Transformational Culture, reflected the business’ continual metamorphosis and reaction to business needs. Driven by global health, economic and environmental emergencies and rising social justice and employee activism, TCM understood that organisations are urgently seeking a new cultural model which will enable them to thrive. The book provides a bespoke blueprint for developing fair, just, kind, inclusive, sustainable and high-performing organisations. Since its publication in 2021, Transformational Culture has been shortlisted for the Business Book Awards 2022 with David being named one of HR’s Most Influential Thinkers.

TCM continues to build from strength to strength, with our sights now firmly set on expansion across the USA. Let’s hope the world is ready.

We have worked with thousands of organisations, from major blue-chip companies including Aviva, Royal Mail, HSBC, BT, EDF Energy, Deutsche Bank, Ford Retail, Shell, American Airlines and BA, to large and complex government departments including the Cabinet Office, Home Office, Department for Work and Pensions, Ministry of Defence and Department for Culture Media and Sport.
