ADB Altorfer Duss und Beilstein AG

ADB was founded in 1969 and today, with around 80 employees, ranks among the larger independent fiduciary firms in German-speaking Switzerland. The Aarau office serves SMEs and private clients from the canton of Aargau in bookkeeping, tax and legal advice, audits and business consulting. The team knows the Aargau tax administration and the cantonal chamber of commerce from years of working together.

Alongside classic fiduciary work, ADB offers business consulting and advice for non-profits. For mandates with a Zurich connection, the team can bring in the Zurich office.
