About Us

Our Story

WilliamsMarston LLC was founded in Boston in January 2014 by Landen Williams and Jon Marston, two former Big Four professionals, who believed that middle-market companies, their investors and lenders were underserved in the accounting advisory and management consulting space. Initially working out of coffee shops and restaurants, the firm quickly landed projects helping a biotechnology and software company to prepare for their initial public offering.

In May 2014, WilliamsMarston hired its first full-time employee and moved into a modest office. As the firm grew, its service offerings expanded into mergers and acquisitions, divestitures, private equity services, interim management, and restructuring. Today, WilliamsMarston has more than 30 professionals and serves over 200 companies in a variety of industries including multinational public companies, market leading private equity firms and many other growth companies.

Although the firm has established larger offices to accommodate its growing teams in Boston and New York, Landen and Jon still fondly recall their first office and first few client wins, all of which remain loyal clients of the firm today.
