In 1928, Howard W. Allen incorporated Missouri, Kansas & Oklahoma Coach Lines, that grew to become a regional intercity carrier serving the nation's mid-section in both regular route and charterbus operations. Diversification efforts in the early 1970's established the company in the commercial real estate business under the name of Venture Properties. Overhauling the corporate structure in the late 1980's, prior to the disposal of the bus operating division, the corporate name was changed to H W Allen Co. in tribute to the founder.

Venture Properties is in the business of investing in, and managing commercial retail and office properties primarily in the Tulsa area. The company currently owns and operates nearly 600,000 square feet of retail space in 14 properties ranging in size from 3,000 square feet to 175,000. The centers are tenanted primarily by locally owned businesses. In addition, the company has been successful in assisting clients in putting together prime locations in the Tulsa and Oklahoma City markets.

The company's interests also include the MK&O Ranch, a commercial cow-calf operation in the Flint Hills of southeastern Kansas, oil and gas exploration, and lease financing through our subsidiary company Landmark Financial Corporation with offices in Denver, Colorado.
