During the difficult era of the Great Depression, the company continued to be entrepreneurial and resumed some of the labor intensive tasks of its earlier years. Building projects were few and far between, so trucks were modified to haul coal and manure from the mines. Sordoni managed to keep most of its employees on the payroll and forged permanent commitments between the company and its personnel.
In the second half of the decade, an upswing in college and hospital construction enabled Sordoni to refine its expertise in the institutional sector. Significant projects were completed for the Wilkes-Barre YMCA, Moses Taylor Hospital, Bucknell University, College Misericordia, and Mansfield and Bloomsburg Teachers Colleges.
