Experience. Innovation. Tradition.

DJ&A, P.C. has professionals board certified in nineteen states.  From the preliminary phases of design to completion, our staff can organize and successfully manage each stage of project development with systematic engineering, surveying and planning, all while keeping close attention to our clients' objectives.

We pride ourselves in being on the forefront of technology and modern practices.  We encourage our professionals to continue their education past the requirements of professional licensing; you will notice we have a Certified Federal Surveyor (CFedS) and a LEED AP on staff. We recently had two projects selected as "case studies" by the Instititute of Sustainable Infrastructure (ISI), in their new sustainable rating system (envision™). We are the only firm in our region to operate a High-Definition Surveying Laser Scanner. 

Traditions are created by two elements - experience and innovation.  Traditions are arrived at by venturing into new grounds of innovation while relying on experience as a guide.  We strive to do both.  DJ&A provides knowledge and stewardship to pass your project through all phases, working with and creating an environment to sustain time.
