A founding belief: putting people at the heart of performance

OREANCE was founded on the conviction that the sustainable performance of an organization rests first and foremost on men and women who are fulfilled in their roles, clear in their mission, and supported in their development. Today, OREANCE structures its expertise around two complementary areas: Management Coaching, led by Harry Abisur, and Executive Search, conducted by Isabelle Vonlanthen.

Our positioning

What sets us apart

OREANCE is not a large network of anonymous headhunters, nor a training organization offering standardized modules. It is a human-scale structure where each assignment is personally handled, with a dedicated contact person from the first day to the last.

This close relationship isn't a default choice—it's a fundamental one. We believe that the quality of a consulting relationship is built over time, on mutual trust, and on a deep understanding of each organization's realities. This is what allows us to intervene effectively, whether it's identifying a CEO in the chemical industry or supporting a manager in the midst of a transition to a new role.
