Constructing the Future
Top level project management and customer service while keeping a “safety first” approach.
Founded in 2009 by Regina Lettau, NNAC was formed as a specialty contracting company geared toward serving military installations and federal customers nationwide. Regina grew up in the construction industry amongst family & close friends who taught her firsthand some of the most important values she manages her company by today; respect, integrity, & hard work. Regina’s executive background began in compliance and federal sector construction administration. In early 2011, Regina accepted certification into the SBA 8(a) program as a Native American, Woman-Owned construction firm.
