George Stone


Upon graduating from Virginia Tech with a degree in Civil Engineering, George pursued a career in construction management, starting in the field and advancing with various companies until forming Building Systems in 1983. After starting Building Systems, he also obtained MBA and Masters in Management degrees. While running the company he also was an Adjunct Instructor in Construction Management at Frederick Maryland Community College for 20 years.

He has been a member of several committees and boards over the years. For many years he was a member of the Associated Builders and Contractors serving on the Board of Directors and Chairman. He also has served as a Trustee and Chair for John Wesley United Methodist Church, on the Board of Trustees of the Washington County Free Library and on the Washington County School Design Review Committee.

George and his wife, Helen, worked together operating Building Systems for 35 years before her retirement. They have two children and three grandchildren. George enjoys woodworking in his spare time and Helen is an accomplished quilter and enjoys reading.

George owes his success to the many dedicated and skilled employees that have worked for the company for many years. The company has a wide range of talents as a General Contractor which self performs carpentry, concrete and building finishes. From George’s engineering background, bridge work and historical renovations have become a specialty.
