The Evolution of Leadership

Founded in 2006, by Vassilis Antonas, Impact is the longest standing Greek firm, specialising in Coaching.

Our mission is to align Performance and Culture with Vision and Strategy. Our expert team achieves this by designing and delivering customised Organisational Development interventions and specialised Training. Our client list numbers well over 100 Multinational and Greek organisations, representing every market sector.

In 2007, we pioneered the first and longest standing Coaching Training in Greece, which was globally the first to receive Accreditation from the Association for Coaching at top tier (AADCT 4/4) in 2014. The course ran for sixteen consecutive years between 2008 and 2024.

In April 2025, we initiated a new groundbreaking training: Trajectory: The Conductor’s Way, was crafted for the uncompromising coaching leader, aiming to maximise impact and optimise potential for themselves and for those in their care. In 2024, it was globally the first Coaching Training to be awarded Accreditation by the Universal Coaching Alliance and, therefore carries dual Accreditation from the AC and the UCA at top tier (Accredited Advanced Diploma in Coach Training).

Our Diploma will launch its next Trajectory in April 2026.

This is Impact. Welcome to The Evolution of Leadership.
