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. WS+B takes its name from Frederick Withum, Leonard Smith, and Ivan Brown, who founded their self-titled firm 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 employee development. At its inception, WS+B's business was conducted by six employees; today, the firm has a staff of 480, including 82 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, and INSIDE Public Accounting. WS+B has 12 offices, located in New Jersey, Pennsylvania, New York City, Maryland, Colorado, and Florida. It is affiliated with HLB International, a global network of accountants and business advisors.
