David is one of the original “founders” of Founders 3 Real Estate Services. Prior to facilitating the merger of three companies to form Founders 3 Real Estate Services, he directed Siegel-Gallagher Management Company to become one of the largest property management companies in the State of Wisconsin and grew the company from five employees to over 260 in seven states across the U.S. His leadership and vision led the company to successfully expand its management platform from traditional real estate into industries such as Marina and Aviation Management. Officially recognized by the Institute of Real Estate Management, Founders 3 earned the industry’s most prestigious designation as Accredited Management Organization (AMO) and has been awarded the 2015 and 2017 AMO of the Year from the Institute of Real Estate Management (IREM).
