The Dahmans took pride in offering the best selection of fresh local products to the retail floral industry. In the early 70s--with the advent of improved transportation and distribution networks, the loss of local growers, and the rising interest in silk, dried, and craft materials--the floral industry changed dramatically. LaSalle Wholesale Floral Company remained in the hands of the Dahman Family until 1990, when the current ownership formed LaSalle WHOLESALE FLORIST INC. at the northwest corner of LaSalle and Ohio Streets.
Although the ownership changed, the company continued selling exclusively to professional retail florists and primarily focusing on providing the highest quality of fresh flowers and greenery. LaSalle WHOLESALE FLORIST INC. rapidly outgrew the original building at 2705 LaSalle. In 1994, the company acquired the business assets of A.G. Beiser Floral Company, including a three-story building at 2730 LaSalle Street, as well as the warehouse building at the back of 2731 Hickory Street.
In October of 1996, LaSalle purchased the 40,000 square foot building at 2744 LaSalle Street that had long been occupied by Windler Wholesale Florist, Inc. After an initial phase of renovations, the company opened for the first day of operations in the new building on January 27, 1997.
