Mazars appoints Erna Versteegden and Mariëtte Turkenburg to the Supervisory Board

2 December 2022 - Mazars has appointed Erna Versteegden and Mariëtte Turkenburg to its Supervisory Board.

Marga Hoek, vice-chairman of the Supervisory Board since the beginning, is stepping down due to the desired diverse replacement of Supervisory Board members as well as her international portfolio. Moreover, Mazars considers it important to add a fourth Supervisory Board member. Important consideration for this is that the Supervisory Board will have a broader approach to supervision and involvement across all service lines. Moreover, a broader Supervisory Board will create even more diversity in knowledge, background and characters, which contributes to the quality of the Supervisory Board and therefor Mazars.

As of this moment, the Supervisory Board consists of Henk Broeders, Pieter Jongstra, Erna Versteegden and Mariëtte Turkenburg.

Attention to quality and to change

Ton Tuinier, chairman of Mazars' Executive Board, is delighted to welcome Erna Versteegden and Mariëtte Turkenburg as members of Mazars' Supervisory Board: "We have come to know Erna Versteegden as an advisor with a strong vision of where quality within our sector needs to move to and what is needed to achieve this. Looking at what is needed from Mazars' role, she will be excellent at overseeing our culture and change agenda and risk management. Mariëtte Turkenburg is an experienced professional and specialist. In addition, we have noticed her passion for strengthening diversity at the top of the Dutch business community. Looking at Mazars, she will be excellent at helping to oversee the tax advisory practice and strengthening diversity."
