About Us


Back in 1963, two entrepreneurial CPAs joined forces to create Mercadien.

One was the owner of his own CPA firm, the other a seasoned accountant and company controller with his own part-time tax business. With their deep involvement in the business community, they saw a need for audit, tax and business advisory services in the central New Jersey market, which had just started to boom.  The gap was there and they were determined to provide the solution.

More than a half century later, we’re proud to say that level of determination continues in everything we do. It’s led to our outstanding growth over the decades. As a multigenerational firm, longevity is one of our hallmarks. In fact, we’re still serving some of our legacy clients and their families today.

Today we focus on four primary service areas: Advisory, Tax, Accounting and Wealth Management; work with a wide range of clients throughout the U.S. and in Europe; have a diverse team of dedicated associates, and invest in the most cutting-edge technology and office facilities to ensure Mercadien remains a firm of the future.


At Mercadien, we believe in leading with passion and commitment. We know our success is directly related to the success of our clients and communities. We take on our clients’ goals and dreams and help bring them to fruition.  Their futures depend on critical decisions based on management, operational, financial and personal discussions that emerge from the utmost trust.
