mdp-lr-05Founded in 1971, Oak was formed when the John T. McShain Company left the Baltimore area to focus on projects in their hometown market of Philadelphia.  During the 1940s and 1950s, McShain’s company became one of the biggest builders in the nation with his most noteworthy projects located in Washington, D.C. including the Jefferson Memorial (1939-41), Pentagon (1941-42), National Shrine of the Immaculate Conception (1959), and John F. Kennedy Center for the Performing Arts (1971).


The late Thomas E. Grey was a Senior Project Manager for the John T. McShain Company at the time they left the Baltimore area.  He agreed to complete the remaining projects in the area including the State House in Annapolis, and formed Oak as a general contractor.  While finishing these projects, Oak began  taking on new work and landed its first project, the Harbor Master’s Office in Annapolis.  From the early years, Oak found a niche in school construction and has had at least one school under construction during every year of our existence.


In 1988, Mr. Grey retired and his son, Thomas L. Grey, moved into the role of President after serving as Vice President for the proceeding 14-years.  Oak continued to grow and was awarded noteworthy projects such as the various village centers in Columbia for the Rouse Company and the Towson Library Expansion, which won an American Concrete Institute Workmanship Award.  At the same time, our firm was also expanding our school construction experience outside of the city into the surrounding counties.  In 1992, Oak completed its first project as Construction Manager, the new Elkridge Elementary School in Howard County.  In 1996, we shifted our focus solely to Construction Management services and continued expanding our expertise in the higher education and K-12 market.


At the close of 2004, Thomas Grey retired and a new management team was chosen. Douglas W. Eder was appointed as President, having previously served as Vice President and Chief Estimator. Gary Murphy was chosen as Vice President, and David M. Rosas was selected as Vice President/CFO.
