Hines has many interests, but none of them involve ketchup. The real estate firm invests in, develops, renovates, manages, and finances commercial real estate, including high-rise office buildings, industrial parks, medical facilities, mixed-use developments, and master-planned residential communities. Its portfolio boasts more than 1,280 properties completed, under development, managed, or invested. They span 100-plus cities worldwide and 516 million sq. ft. Hines has collaborated with such world-renowned architects as I. M. Pei, Philip Johnson, and Frank Gehry. Management services include marketing, tenant relations, and contract negotiations. Chairman Gerald Hines founded the family-controlled firm in 1957.
