He moved to Seattle in 1959 to attend the University of Washington School of Art, where influential teachers included Walter F. Isaacs, Spencer Moseley, Bob Jones, and Wendell Brazeau.

[4] From the early 1960s Steensma's work was shown in Seattle galleries such as the Kinorn and Francine Seders, and in 1965 he won First Prize in painting at the Pacific Northwest Arts and Crafts Fair in Bellevue, Washington;[5] however, he suffered from manic-depressive illness, and by the mid-70s his erratic behavior had largely alienated him from the arts community.
