Bill started Diamond Decks, now recognized as a leading deck builder in Anne Arundel County, MD, because he was tired of watching contractors chase volume over quality. The company was built on a different idea: one job, one site, one owner paying attention to every detail. Three decades in, that is still how every project gets run.
