Diabolo is renowned for world class coaching of executive leaders in commercial enterprise and public service.


We are experts in delivering best practice coaching for individuals and leadership teams. Diabolo Limited, established in 2003 and led by Karen Dean MCC (Master Certified Coach), is continually raising the bar on leadership performance and the ability to inspire.


We deliver coaching through a non-directive model, which believes in the client’s capability to find their best solution. The coach will ensure that clearly articulated goals are defined, as the coaching contract is established. Measures of success are vital if return on investment is to be evaluated.





Diabolo Limited is proud of its superb network of skilled, passionate and experienced coaches who offer a diverse mix of talent. This ensures the best possible matching with the client profile, context and need. 


All our Associate Coaches are credentialed members of the established professional bodies, International Coach Federation or World Association of Business Coaches. We are signed up to a code of ethics and engage in regular supervision of our coaching practices. We are committed to continuing professional development.

Additionally every one of our coaches is a thought leader in a specific aspect of coaching. From developing unique methods in team coaching, delivering accredited training of coaches and supervisors, building internal coaching teams, supervising other coaches, bringing together quality coaching resources and originating e-coaching tools. Our associates have an exceptional profile.
