Duncan Müller


Duncan specialises in Leadership Development and Team Development and has been with Global Warriors since 2015.

His purpose is to unlock the potential of leaders and teams so they can create the world they imagine – whether it’s developing courageous leaders who speak their truth, compassionate leaders who get the most out of people or creative, intelligent, high-performing teams. 

He works across various sectors including marketing and media, financial services, IT and HM Prisons. 

  • Certified Professional Co-Active Coach (CPCC)
  • Certified Organisational and Relationship Systems Coach (ORSCC)
  • Professional Certified Coach (PCC) with the International Coach Federation.  

Duncan loves his work and is passionate about taking it further into the world, as a trainer in one-to-one coaching skills (Coaching for Performance) and specialist team coaching skills (Organisation and Relationship Systems Coaching, or ORSC).

Duncan understands life can be challenging and involve difficult decisions. He left South Africa in 1998 to build a new life in the UK, gaining his MBA part-time while working in the fast-paced advertising industry, and going on to build a second successful career as a coach.

Before training as a coach, he spent more than 20 years in the creative and marketing industries, mostly within senior client services roles. He’s experienced leadership (good and bad) and led many teams across many organisations.

A lover of learning and development, he’s trained at some of the world’s leading coaching schools including the Coaches Training Institute, the Centre for Right Relationship, Team Coaching International, The Leadership Circle and the Firework Coaching Company. In addition, he holds a BA in Fine Art, various marketing qualifications, and an MBA.

When not working, Duncan enjoys spending time with his Tracy (his wife), running, drawing, theatre, films, gorgeous food and travel. 

Words of Warrior Wisdom:

I have two I try to live by: “Make your destiny.” and “Endless possibilities.”
