Our team of industry leading experts pair Big Four experience and strong technical expertise with the passion, talent, and drive to deliver successful outcomes in the most challenging situations. The firm was founded in Boston in 2014 by two former Big Four professionals who believed that middle-market companies, their investors and lenders were underserved in the accounting advisory space. Initially working out of coffee shops and restaurants, our advisory firm quickly landed projects helping a biotechnology company and a software company to prepare for their initial public offerings. In 2016, we opened our New York office and appointed a New York market leader. As we grew, our service offerings expanded to include technical accounting, mergers and acquisitions, divestitures, Private equity services, interim management and restructuring.
