Our firm was founded in Düsseldorf in 1980. Dr. Harald Schotenroehr was joined by Ernst Günter Hansen in 1993 and Cäcilia Voets in 1994. In 2002 Thomas Ernst Müller became new partner, thus forming HSMV - Hansen Schotenroehr Müller Voets.

At the end of July 2011 the partnership was transferred to a partnership company (“Partnerschaftsgesellschaft”), which at present employs more than 55 professionals, who work in the areas of auditing, tax consultancy and business consultancy. In August 2011 Martin Rohkämper, in November 2011 Ralf Corterier joined HSMV. At beginning of 2014 Christoph Bergedick and Christian Vonderreck joined the partnership company.
