Those who visit the newly opened Lewis Drug store on Louise Avenue in Sioux Falls, S.D., undoubtedly will see the “new face” of the company, according to president and CEO Mark Griffin. This new store includes a “Four Seasons" department, a 4,000-sq.-ft. environmentally controlled room that can be used for various purposes throughout the year. For example, in the winter months, it can be used to display live Christmas trees that will be kept at 45 degrees, and in the spring, it can be used as a garden shop.
