Dennis Gunn is the Owner and CEO of D.R.G Construction. He has had years of experience in all phases of Marine Construction since 2002 operating as Dr. Dock. Building Navy Bulkheads, Floating Docks, Ramps, Boat Lifts, etc he is an expert in all phases of Marine Construction.

After Hurricane Irene hit back in 2011 Dennis recognized the lack of options Long Islanders had in terms of fixing their bulkheads to protect themselves from devastating storms. He then formulated a plan and opened up D.R.G. Construction. He’s developed strong relationships with Building Departments and Insurance Companies making the process go as smoothly as it can for his customers. He’s built a very resourceful crew with hard-working ethics that get the job done.

Joseph Sagona
We recently had our bulkhead wall resurfaced by Long Island Marine Construction-DRG Construction. DRG is a family owned and operated company where everyone works well together. Their work is superior, and they communicated with us during every step in the process. Their team is pleasant and polite. The work was finished quickly with no issues! Thank you DRG!
