DMY projects in the Commonwealth of Virginia

Public Sector


On January 11, 2010, DMY Engineering Consultants was born. In just six years DMY grew from an AASHTO certified lab operating out of our founder Wayne Ma’s garage, to a 50-person firm with three offices, nine Professional Engineers and a presence at some of the largest project sites in the Washington metropolitan area. All of this would have been impossible without the hard work and dedication of our staff and the trust of our many clients and partners. We look forward to many more years of success and many more anniversary celebrations!
