Where we come from
From its humble beginning to the international Group that it is today, Mazars has always remained true to its founder’s spirit and values of deep ethical commitment, responsibility and belief that technical excellence is the key to success.
It is based upon these values that the generations which inherited Mazars managed to grow the organisation, through the co-optation of new partners, in Europe and around the world, and through mergers with firms that share the same values, vision, and objectives.
That well known national firms like Weiser in the USA, Neville Russell in the UK or Paardekooper Hoffman in The Netherlands, elected to join the partnership is proof that the Mazars way has indeed been an attractive and effective model.
Now operating via its integrated partnership in
89 countries and territories across the globe, with over
professionals, Mazars has become a fully-fledged global player.
