As founder of the predecessor company, and its steward for over thirty years, Mark is recognized as one of the preeminent leaders of the commercial real estate industry. He provides Rubenstein Partners with extraordinary perspective and insight gained through his many years of experience.
In 1965, Mark joined Builders Development and Service Company of Philadelphia. While employed there, he managed in excess of 1,500 apartment units in Pennsylvania and Delaware and developed over 700 new units along with two branch banks, a convenience food market, a 33,200 square foot supermarket and the first phase (200,000 square feet) of an enclosed regional mall shopping center. During this period, he also planned, zoned, developed and sold several hundred acres of land as tracts for single-family housing.
In June 1969, Mark formed The Rubenstein Company, which then assumed responsibility for the completion and future management of all the projects at his former employer that were still in the developmental stages. The basic construction and bookkeeping staff of the former company joined his firm.
In a measured program over thirty-five years, Mark guided development of the predecessor company into a full service real estate company with capacity for acquisition, development, construction, leasing, management and financing of substantial real estate projects.
