During the early 1970s, Houser continued to teach at the Institute and began the rigorous production and exhibition cycle for which he became well known. As head of the sculpture department, he felt compelled to work in as many sculptural media as possible, evidenced by his solo exhibition of stone, bronze and welded steel sculptures at the Heard Museum in Phoenix, Arizona in 1970. The following year, Houser exhibited paintings and sculpture at the Philbrook Museum of Art in Tulsa, and in 1973 was awarded the Gold Medal in Sculpture at the Heard Museum Exhibition.
