Under the theme “A Journey”, the Luxembourg office of GSK Stockmann celebrated its 10th anniversary with a recent event in its Luxembourg office attended by more than 220 guests, including ministers, excellencies and ambassadors as well as clients, business partners, colleagues, and friends from Luxembourg and abroad.

Following an inspiring speech by Luxembourg’s Minister of Justice, Elisabeth Margue, about the Grand Duchy’s legal and judicial system, Luxair CEO Gilles Feith gave a keynote address about Luxembourg as a hub, introducing the company’s collaboration with Luxair alongside Luxembourg artist Sumo.

The premiere of the firm’s new image video, showcasing milestones of the past decade and introducing intriguing upcoming projects, served as the program’s high point.

A concert by the talented violinists Eleanna Stratou and Leo Strelle of the Luxembourg Philharmonic Academy concluded the official part of the event – along with the birthday cake being presented and cut by the three founding partners of the Luxembourg office, Dr. Marcus Peter, Andreas Heinzmann and Dr. Philipp Mössner.

Today, more than 60 professionals call this office home — not because the hours demand it, but because the culture, the people and the quality of what we do together make them want to be here. What makes me proudest is not the growth itself but how we grew — organically, through talent nurtured in-house, without ever imposing a culture of billable hours pressure and without ever compromising on who we are. It works.” – Dr. Philipp Mössner | Partner | GSK Stockmann.
