21 Delta Engineers
Paul Mattern was introduced to NBDC through a flier advertising the Veteran Business Owners Forum breakfast. Since attending the event, his business 21 Delta Engineers has grown through similar networking opportunities. 21 Delta Engineers, LLC is an engineering consulting and construction company specializing in mechanical, electrical, physical and electronic security, audio visual and fire protection systems.
Founded by Mattern in 2008, the company is a participant in the NBDC’s Federal Contractor Certification Program. In military terminology, “21” is the engineer series and “Delta” signifies facility engineers. Mattern and two others serve as 21 Delta’s design and construction engineers.
