Marine Construction, Inc. stands behind every job we do. Our dedicated office and field personnel take pride in delivering a quality project on each and every job. We are a full service construction company that handles every aspect of the job from design to permitting to building and maintenance.

Dan Coston — Owner and President

A veteran of the U.S. Air Force, Dan brings a steadfast commitment of integrity and service to our clients. He is the owner of Marine Construction, Inc., specializing in dock building, boat lifts and seawall construction and Coston Marine Services, which specializes in dredging, heavy marine work and erosion control. He is also the owner of Environmental Permitting Associates, which specializes in obtaining the permits required for our jobs. Born and raised in Florida, Dan spent his summers building docks and seawalls with his father, Dave Coston who, at that time, owned Trident Marine. After returning from the Air Force, Dan and Dave formed Coston Marine. Then, looking to expand, in 1999, Dan acquired Marine Construction, Inc., earning his Marine Contractor’s License in 2003. Steady at the helm, through the boom of the early 2000’s, three hurricanes and the recession of the late 2000’s, Dan’s history and experience brings to our clients a company they can count on.

Larry grew up in Palm Beach County, spending much of his time around boats and the water. At age 15, he began working in construction, after being hired by the father of a friend. This led him to obtain his Florida General Contractor License at the young age of 24, which he still maintains today.
