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.

Recent Client Testimonials

D.R.G. was wonderful to work with. The staff is very nice and helpful. Dennis, the owner, is a great guy and is very knowledgeable about marine bulkheads. I had my bulkhead redone and I’ve never been so confident in the integrity of my bulkhead in the 20 yrs that I’ve owned my house! I finally have peace of mind! Thank you, Dennis!
