Better Leaders for a Better World

THE ART OF LEADING

The THIERRY graduate school of Leadership in Belgium fostered its genuinely universal roots since its inception in the year 2000. For nearly three decades the talent development of leaders towards mastery in the art of leading, formed the main path and primary goal of the THIERRY learning approach. In most recent times the originally Belgian school modified its worldwide and future-oriented role in leadership education and research, and in leader development.

SINCE SEPTEMBER 2025

Having pursued a very gradual transformation, the school has adopted a new shape and structure. Since September 2025 the educational activity is hosted in a new entity called  TRAUNOS, active solely at the highest leadership echelons in organizations. TRAUNOS, the successor of the DR Leadership unit of the school (see further below), addresses the challenges for top leaders (CEO and equivalent roles) in view of the major planetary changes envisioned in the coming three decades. 

UNTIL 2025 (historical facts)

· The THIERRY think-tank initiated in the early 1990s by the school's founder, and previously called LEUDANCE Research, continues its activity that is anchored in the primal and unbiased meaning of the terms leader, leading (to lead), and leadership. While retaining its practice-oriented and multidisciplinary scope, since 2025 the research supports the TRAUNOS unit's mission. 

· Offered since 2002, the curricular programmes leading to a post-graduate diploma, or a masters or PhD degree in leadership (supervised by the International Higher Institute for Leadership (INSIL) since 2010), have been phased out completely in 2024.

· In light of the global climate change challenges, the i2LN -- Icare Institute for Leadership and Nature -- pursued a specialist mission from 2014 to 2022, embodying the THIERRY graduate programmes in Environmental Leadership launched in 2002 - the world's first online curricula in that domain and of that level.  

· In accordance with the school's prior "Plan 2020-2025", the DR Leadership unit led by Jean-Pierre Bal, founder of the school, had meanwhile remained unchanged. DR was active since more than two decades in the design and delivery of the made to measure top-level leadership development programmes called CHRONOS - solely at CEO level, for emerging or in-office leaders of various types of organisations, including corporations, nations, governments, monarchies, and leading families. Reportedly among the few best in the world, yet also known to be most trying for its participants, the bespoke CHRONOS and coaching mode are tailored for one person at a time, with utmost confidentiality assured. That proven approach is since fully integrated into the TRAUNOS activity unit.
