About Withum

Headquartered in Princeton, N.J., Withum provides a long list of services, including accounting, auditing, employee benefit services, pension plans services, tax services, litigation support, business valuation, insolvency services, transaction advisory services, and management consulting. The firm has also expanded to include digital and technology transformation services, cyber and information security services, and outsourced accounting systems and services for clients.

The firm takes its name from Frederick Withum, Leonard Smith, and Ivan Brown, who founded their self-titled company in 1974 in Middlesex County, N.J. The firm’s founders began their careers at larger accounting firms, and when they struck out on their own, their idea was to provide personalized service to companies that were still growing. They also decided that they wanted their firm to be "people-focused," putting the emphasis on both client service and staff development.

At its inception, Withum’s business was conducted by six professionals; today, the firm has nearly 1,300 team members, including nearly 150 partners and principals, many of which contribute articles and perspectives to major news and trade media such as The Wall Street Journal, Fox News Channel, Financial Executive Magazine, and INSIDE Public Accounting. Withum has 15 offices, the majority of which are in New Jersey; the firm also has offices in the Cayman Islands, Massachusetts, New York City, Orlando, Philadelphia, Southern California, Virginia, and Washington, D.C. It also recently launched an office in Bangalore, India.

Withum is currently the 26th largest firm in the country, as measured by annual revenues, and most of its offices have more than 100 team members. It is affiliated with HLB International, global network of accountants and business advisors.
