Sears and Marguerite moved to San Mateo, California about Summer of 1942, where a Baháʼí Spiritual Assembly had lapsed, and he gave an especially noted talk about using radio to promote the religion. In San Mateo they were visible giving talks on the religion as late as February 1944. He embarked on a national tour in 1945, beginning with talks in the New York City area in February, then after a break gave 48 talks across August and September through Salt Lake City, Laramie, Denver, Omaha, Topeka, Kansas City, Independence, Milwaukee, Omaha, and into Canada in November, as well as Charlottetown. He was back in New York in December giving a talk and participating in a statewide conference of Baháʼís. During this period he was also on a committee that consulted on Baháʼí use of radio with Mildred Mottahedeh, prominently appeared at a peace banquet with Dorothy Beecher Baker (also a future Hand of the Cause), gave talks in 1946 at a meeting in Los Angeles with scholar Marzieh Gail, and helped produce a higher profile radio segment in Denver. There is a gap in public coverage of any talks until 1952, though his behind the scenes work continued and began to weave into his rising profile in the public eye and his service to the Faith.
