After the war she taught classes at the San Diego Fine Arts Gallery. Although best known for her sculpture in bronze and ceramic, she also worked in pottery, watercolors, enamel on copper, and glass tile mosaic. Among her architectural projects were figurative groups for the Burnham and Prudential buildings in San Diego, and a portrait relief of Dean Peterson for San Diego State College.

To help speed her recovery, long-time friend Donal Hord gave her encouragement to keep creating works in sculpture. Churchman died in Chula Vista, CA on Feb. 25, 1988.
