35 years of Advartis Group – building growth together 


35 years ago in Warsaw began the journey that led to the creation of the Advartis Group. This is not only a story of our organization’s growth, but also of partnerships with clients and the dedication of our employees. Learn more about this unique path. 

First steps 

We started in 1990 as the law firm TGC Corporate Lawyers. Our first office was located in the center of Warsaw, right by Saski Park, on Królewska Street. It was modest, but full of energy and ideas. 

From the beginning, our mission was to support foreign companies entering the Polish market. They needed a partner who understood the local legal and business environment. Over time, we began offering them additional services: HR and payroll, accounting, tax advisory, audit, and consulting. From the very start, we developed in step with our clients’ needs, keeping pace with the transformations of the Polish market and the wider business world. 

Shared growth 

Many of our clients, whom we remember as small startups, are today large and successful enterprises. We grew alongside them. From a small law office, we have become one of the leading advisory and BPO groups in Poland, the Czech Republic, and Slovakia. 

Today, under the brands Crowe, Contract Administration, and TGC Corporate Lawyers, we support companies in the most important aspects of running a business. We accompany our clients at every stage of their development – from market entry to international expansion. 

How do we support clients? 

A stable partner in a changing world 

What truly sets Advartis apart are its people. Thanks to them, for 35 years we have been a reliable and trustworthy partner to our clients . Over 20% of our team has been with us for two decades — not only an impressive figure, but above all a testament to mutual trust and shared values.  This has provided the foundation for long-term relationships with our clients, many of whom have also worked with us as a trusted partner for twenty years or more. 

Over the years, the economy, technology, and market expectations have changed. We too moved forward, expanding our expertise, while always relying on the same foundation – people and relationships. The culture of the Advartis Group is built on this foundation, giving us the strength to look to the future with confidence. 

Christian Fielding, Advartis Group CEO:

Our firm began with great ambitions and aimed high from the start. Where we are today is the result of the dedication of our people and the trust of our clients. I am extremely proud of the journey we have taken together. –I thank everyone who has built and continues to build our story. 

We thank all those who are part of our journey. The best is still ahead of us.
