Who We Are

WithumSmith+Brown began with a vision...

Having first started their careers with "Big Eight" accounting firms, WS+B's founding partners, Frederick Withum, Leonard Smith and Ivan Brown, saw an opportunity to serve growing companies that needed expert advice along with personalized and timely services. The firm they envisioned would be client-focused and employee-friendly. It would provide a professional and caring environment where talented, people-oriented professionals could reach their potential, where all clients would receive responsive attention to their needs and where the highest professional and ethical standards would be upheld.

Our firm's founding principles of dependability and exceptional service along with its people-focused philosophy have been the cornerstone of our success and fine reputation for more than 30 years. Clients know they can trust WS+B's highly skilled professionals whose expertise in accounting, auditing, taxation and consulting has repeatedly assisted businesses in realizing their full potential.

Incorporated in 1974 in Middlesex County, New Jersey, with a total of just six employees, WS+B now operates offices in New Jersey, Pennsylvania, New York and Maryland. The firm also employs approximately 375 dedicated individuals, over 185 who are CPAs.

Today, WS+B's capability to service clients also spans far beyond the regional area. Through our affiliation with HLB International, a worldwide organization of accounting professionals and business advisors in more than 100 countries, we provide specialized business services to help international companies succeed in the global market.
