In 1980 Angus McDowell and a small group of CA’s in New York got together to form a network to assist each other in their professional careers in the United States.
ACAUS expanded across the United States, focused on communications, education, reciprocity and other professional and social activities. ACAUS flourished due to the efforts of its volunteer members reaching a national membership of over 7,000.
In 2020 ACAUS became Chartered Accountants Worldwide Network United States, further defining the association as a major international accounting body.
