Interview with Matthias Dudler


In addition to asset management, you offer your clients courses with horses and games with donkeys. What prompted you to do this?

There are about 2500 external asset managers in Switzerland. More or less all companies offer their clients the same thing. As an asset manager, I would like to break new ground in addition to our traditional business and offer my clients and their families something special, unique and unforgettable. It is my concern to create added value and to focus on nature and animals, which give us balance and energy. I want to teach the children care and respect. Besides managing clients' money, this is a very nice job. 





A Country Estate with Granary

With office space on an estate and a beautiful conference room in a granary dating back to 1769, we convey to our partners and clients the Old-style Swiss Private Banking that we live. Our asset management company offers a location of idyll and seclusion to work and meet in peace.
