About JS-International

JS-International is an international business focussing on the development of international leaders and leadership teams. We work in partnership with leaders to help them achieve their desired personal and professional transformations. Our belief is that development and change is about going to the edge, exploring and breaking through boundaries, helping people and businesses to achieve what they might have thought previously was impossible.


We facilitate real team experiences and conduct team coaching to use as vehicles to explore leadership and teamworking and we conduct Executive Coaching.


We work to unleash the skills of leaders and leadership teams to enable leaders to be:


  • able to embrace innovation

  • change resilient

  • coaches themselves

  • more disruptive thinkers

  • more strategic

  • digitally fluent

  • tackle the challenges effectively of the next decade

We look at organisational leadership which means developing leadership teams at all levels within an organisation to enable leadership across boundaries – functional, organisational or sector.  The lens is a dual focussed leadership approach that works towards what it best for teams and what is best for the organisation as a whole, simultaneously.  It is also about encouraging a systemic mindset that delivers organisational passion and loyalty.

Sally Jackson & Jan Versteeg

We deliver customised programmes in-house for leaders and we also deliver public programmes in Malta focusing on personal and professional development through our NLP and Neuroscience course (accredited by the American Board of NLP) and our Coaching Course (accredited by the International Coaching Federation).


Jointly owned by Sally Jackson and Jan Versteeg, JS-International is also supported by a range of world-class coaches.   We carefully select these experts in their field to deliver customised solutions for our in-company work. This means we put together “Virtuoso teams” specifically for the event for each client, ensuring world-class quality and the latest thinking.


JS-International has developed a proprietary 360 degree feedback tool based on years of working with thousands of leadership teams over the past 20 years.  This tool is based on our leadership philosophy that is called CORE© leadership.   Core stands for Collaborate, Ownership, Respect and Engagement.
