A story that matters

We believe that we’re only as good as the good we do.

All the facts and figures that talk to our size and diversity and years of history, as notable and important as they may be, are secondary to the truest measure of Deloitte: the impact we make in the world.

So, when people ask, “what’s different about Deloitte?” the answer resides in the many specific examples of where we have helped Deloitte member firm clients, our people, and sections of society to achieve remarkable goals, solve complex problems or make meaningful progress. Deeper still, it’s in the beliefs, behaviors and fundamental sense of purpose that underpin all that we do.

With over 150 years of hard work and commitment to making a real difference, our organization has grown in scale and diversity—approximately 263,900 people in 150 countries and territories, providing audit, tax, legal, financial advisory, risk advisory, and consulting services—yet our shared culture remains the same.

For us, good isn’t good enough. We aim to be the best at all that we do—to help clients realize their ambitions; to make a positive difference in society; and to maximize the success of our people. This drive fuels the commitment and humanity that run deep through our every action.

That’s what makes us truly different at Deloitte. Not how big we are, where we are, nor what services we offer. What really defines us is our drive to make an impact that matters in the world.

“Deloitte” is the brand under which tens of thousands of dedicated professionals in independent firms throughout the world collaborate to provide audit, consulting, financial advisory, risk management, tax and related services to select clients. These firms are members of Deloitte Touche Tohmatsu Limited, a UK private company limited by guarantee (“DTTL”). Each DTTL member firm provides services in particular geographic areas and is subject to the laws and professional regulations of the particular country or countries in which it operates.

Each DTTL member firm is structured in accordance with national laws, regulations, customary practice, and other factors, and may secure the provision of professional services in its territory through subsidiaries, affiliates, and other related entities. Not every DTTL member firm provides all services, and certain services may not be available to attest clients under the rules and regulations of public accounting.

DTTL and each DTTL member firm are legally separate and independent entities, which cannot obligate each other. DTTL and each DTTL member firm are liable only for their own acts and omissions, and not those of each other. DTTL (also referred to as “Deloitte Global”) does not provide services to clients. 

The DTTL member firm in Korea is Deloitte Anjin LLC. For more information about Deloitte Anjin LLC, click here.
