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 and their investors and lenders were underserved in the accounting advisory space. Initially working out of coffee shops and restaurants, the pair quickly landed projects helping local biotechnology and software companies to prepare for their initial public offerings.

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 25 professionals and serves over 125 companies in a variety of industries including dozens of multinational public companies, market leading private equity firms and many other growth companies.

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