Company History

Originally incorporated in 2000 by the late Dr. Kris R. Nielsen as a subsidiary of the Nielsen-Wurster Group, Pegasus-Global was acquired by Dr. Nielsen when the parent company was sold to Marsh USA in 2008. That year, the company’s headquarters were moved to Cle Elum, Washington, 80 miles southeast of Seattle.

Also in 2008, Dr. Patricia D. Galloway purchased 51% of the stock to become a second shareholder. She became the sole shareholder after Dr. Nielsen’s passing in 2013. In 2018, William Riggins, formerly the firm’s executive consultant, purchased 49% of the stock and was named president and CEO. At that time, Dr. Galloway became chair of the Board of Directors. Later that year, former clients Mike Chilton and Vineet Mohan purchased 41% of the stock from Dr. Galloway.  Mr. Chilton became Executive Vice President and COO, and Mr. Mohan became Executive Vice President and CFO. Jeremy Clark serves as Vice President. Today, with its roster of uniquely qualified management consultants, the company is recognized as a leading firm in the management of megaprojects.
