Executive Leadership Team
The company’s founders and owners Sean Keegan (left) and Nick DeSarno (right) – both native Washingtonians, with strong roots in the area – started Rock Spring Contracting in March 2010. The two combined their previous work experiences in construction and painting to concentrate on building a company that would focus on customer service, dependability, efficiency, and quality. Rock Spring Contracting, named after their respective hometowns, Rockville and Silver Spring, was born.
