About Jonathan Warner

Jonathan Warner is a specialized firm that supports boards, managementteams and leaders to improve their effectiveness and helps to strengthen leadership throughout the organization. We serve a diverse clientele, running from international corporations to public organizations.

Our services include: • Team analysis and composition • Board dynamics and executive collaboration • Executive assessment and leadership audit • Self-evaluation of supervisory boards • (Executive) coaching and leadership programs • Leadership development for future leaders

Assisting the (senior) leadership of an organization requires a confidential, personal and indeed, modest attitude and approach. That is exactly what we offer. Our aim is to provide evidence based solutions that truly fit the needs of our clients, allowing their leaders to make the difference.

As no other consultancy firm, we combine decades of senior management experience with the newest insights from psychology. We understand board-, founder- and teamdynamics and we have solid knowledge of the state of the art in corporate governance.

When working with Jonathan Warner you may expect an integrated approach, tailored to your needs, not our service offering.
