Our Commitment

The big picture

Our social and cultural commitment is a fundamental part of our corporate culture. As a result, we not only feel that we have an obligation to serve our clients but also perceive ourselves as an active member of society.

Fully conscious of our responsibility, we organise and support social and cultural projects at every level.

Funding of the arts

Modern art has been integral to our company for years and is a natural part of both our working environment and our commitment.

Art gives us food for thought and encourages us to take a creative approach to dealing with the world that exists outside our own front doors.

We support art projects of all kinds and offer regular opportunities for artists, predominantly from this region, to present their works within the scope of exhibitions at our firm. All proceeds earned from admission to these exhibitions are donated in full to a social project.

Youth = Future

If we want to safeguard the future, we have to consider our children’s interests first and foremost.

Our commitment to working with children and youth is therefore firmly anchored in our corporate culture as well. Conscious of our special social responsibility, we support and promote numerous individual projects, initiatives and facilities.

Your questions will then be answered directly by our office staff or forwarded to the relevant contact within the firm.
