Company History and Firm Profile

The origins of our firm reach back to the early 1950s, when several audit and tax professionals formed various professional service firms in Riverside and other areas of the region. Through the years there have been mergers, acquisitions, and other changes; but our roots remain deeply embedded in the Inland Empire area of Southern California.

In 2000, these professionals with decades of combined experience decided to merge their expertise and form a professional services firm with a unique synergy of knowledge, service, teamwork, and an historical sense of our role in the development of the inland area over the last 60 years. From that formation, Ahern Adcock Devlin LLP (AAD), a highly successful, growing company that continues to lead and expand into the twenty-first century, was born.

AAD provides tax, audit, and accounting services to businesses, non-profit organizations, and individuals.
Knowing your business is our business. Every client relationship is a partnership in which we share

education and experience are among the region’s best, we strive not only to meet but exceed our clients’
