About Withum

Headquartered in Princeton, N.J., WithumSmith+Brown 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 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 a staff of over 800, including more than 110 partners, 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, Forbes.com and INSIDE Public Accounting. Withum has 15 offices, the majority of which are located in New Jersey, Maryland, and Massachusetts; the firm also has offices in New York City, Philadelphia, Orlando, and the Cayman Islands. 

Withum is currently the 25th largest firm in the country and 6th largest in the Mid-Atlantic region, as measured by annual revenues, and the majority of its offices have more than 100 team members. It is affiliated with HLB International, a global network of accountants and business advisors.
