Our Mission

Aria's mission as a group of professionals is to provide high quality audit work allowing its clients to accomplish their true growth and development over the medium to long term.
In order to fulfill this mission, Aria has settled on three operating principles.

Pursuit of Professionalism

We support medium to long-term growth and development of our clients through a rigorous but fair audit process.

As organizational forms have diversified and business operations have become more global in recent years, we offer a service comprising the most suitable audit techniques corresponding to the individual corporate structure and type of business operation of our clients. In addition, we effectively integrate the impact of globalization in accounting standards and adapt this to our clients' increasingly global focus.

Establishment of trust

We value the establishment of a high level of trust with our clients as without this trust, it is more difficult to perform an effective audit.

We maintain our trustworthiness as a professional accounting firm and thus seek to obtain the trust of our clients through a sincere and genuine approach as envisaged in our mission.We value the establishment of a high level of trust with our clients as without this trust, it is more difficult to perform an effective audit.
