1968  On March 16, 1968, Lester H. Poggemeyer, P.E. opened a two-man office in Bowling Green, Ohio, and began providing engineering services to public and private clients.

1975-1985 In 1975, we established our first branch office in Lexington, Ohio.  Lexington continues to this day to be important for PDG. We are thankful for our on-going relationship with the Village of Lexington and have helped with nearly 200 projects and look forward to continuing our excellent working relationship.
1982 was another exciting year at PDG. We opened offices in the City of Defiance, Ohio; and Las Vegas, Nevada. These offices continue to thrive today.
The Las Vegas office works closely with public and private clients as that region continues to grow. They assist with large public high profile projects – most notable is the beautification of the famous Las Vegas Strip.
The Columbus area office was opened in 1985 to provide better services to our clients in mid and southern Ohio. Today, the office is located in Hilliard, a suburb of Columbus, from where PDG provides services to communities, such as New Lexington, Adams County Regional Water District, and communities in between.
