"I have not found any contractors except S. J. Amoroso that from the start and consistently throughout the project, to be so completely collaborative by steadily suggesting solutions whenever difficulties arose without getting mired in who was responsible for creating the difficulty before working on a solution." Charles Wren, PMP, LEED AP, Deputy Program Manager ~ Los Angeles Community College District
