A true member of the American Renaissance, Post engaged notable artists and artisans to add decorative sculpture and murals to his architectural designs. Among those who worked with Post were the sculptor Karl Bitter and painter Elihu Vedder. Post was a founding member of the National Arts Club, serving as the Club's inaugural president from 1898 to 1905. In 1905, his two sons were taken into the partnership, and they continued to lead the firm after Post's death, notably as the designers of many Statler Hotels in cities across the United States. From that time forward, the firm carried on under the stewardship of Post's grandson, Edward Everett Post (1904–2006) until the late twentieth century.
