Our History

Since our founding in 1963, the BDO story has been one of continuous response to our clients’ and our people’s ever-changing needs. Our history is relevant today because our clients value the continuity and stability of a global organisation that has developed so successfully over more than sixty years. Equally, our partners and staff know that they are working for a well-established organisation that is built upon clear values and a successful past.

The initial international organisation was known as the Binder Seidman International Group, formed by respective firms that were already well established in Canada, Germany, the Netherlands, the UK and the USA, and wished to share and expand their knowledge to better serve their clients. 

In 1973 the organisation adopted the name BDO, made up from the initials of the three founding European firms: Binder (UK), Dijker (Netherlands) and Otte (Germany).

We’re proud that in the subsequent 60+ years, BDO has grown into a US$14 billion+ business, operating in 166 countries. We have achieved this by adapting to the changes brought about by external forces such as regulation and globalisation, as well as the changing needs and expectations of our clients.
