Casco1

CASCO + R|5 evolved from a civil and structural engineering firm originally established by E. George Cassis, P.E. in Litchfield, Illinois in 1959.  Mr. Cassis was a Civil Engineer, earning his B.S. at the University of Missouri, his M.S. at Yale, and ultimately his Ph.D. at Yale and Columbia Universities. Mr. Cassis relocated his firm to Kirkwood, MO in 1962 and it became incorporated as Cassis Associates, Inc. in June of 1963.  Around 1965, in a joint venture with William en Tao and Associates, Cassis Associates built a new office building at 2357 59th Street in south St. Louis.  The new facility was shared by both firms

Within a year of the firm’s inception, services were extended to include architectural work for commercial and industrial clients. Subsequently, services were expanded to cover site selection, interior furnishings, mechanical and electrical work, industrial engineering, materials handling and construction management.
