About Mazars

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 in 103 countries and territories around the world, we draw on the expertise of 50,000 professionals – 33,000 in the Mazars integrated partnership and 17,000 via the Mazars North America Alliance - to assist clients of all sizes at every stage in their development.
