Founded in 1929, we are a recognized leader in the Mid-Atlantic (LF Driscoll) and Northeast (LF Driscoll Healthcare) for prov ... iding top tier construction management on projects ranging from less than $1 million to over $2 billion. Leon F. Driscoll started LF Driscoll under the cloud of the Great Depression, a time when reputation was paramount, and perseverance was the only lasting measurement of success. Our company built this reputation through old-fashioned hard work and dedication, which remain at our core today. The collective talent and expertise of our people, clients, and partners have resulted in hundreds of buildings that pioneer research, advance medical treatment and patient care, showcase art and entertainment, preserve cultural treasures, and educate generations. In 2009, we joined a growing family of companies known as STO Building Group. The STO Building Group family of companies—Structure Tone, LF Driscoll, Structure Tone Southwest, Pavarini Construction Co., Pavarini McGovern, Govan Brown, Ajax Building Company, BCCI Construction, Layton Construction, and Abbott Construction—includes over 3,500 employees located in offices throughout the US, Canada, UK, and Ireland. read more
