Who We Are

About
AGDM

Built on the Water, Driven by Results

Atlantic & Gulf Dredging & Marine, LLC is a specialized dredging and marine construction company headquartered in Indiantown, Florida. Founded in 2014, AGDM was built on a simple premise: deliver dredging projects on time, on budget, and with environmental protection built into every hour of every operation.

Today we operate across Florida's Atlantic and Gulf coasts, executing hydraulic and mechanical dredging projects for federal, state, and municipal clients. From the Intracoastal Waterway to barrier island beach nourishment, our work keeps Florida's waterways navigable and its coastlines protected.

Rooted in Tradition

AGDM is a locally owned, Native American-owned enterprise. Its principal is an enrolled member of the Pokagon Band of Potawatomi Indians, bringing a deep respect for environmental stewardship and natural resource management that is woven into every project we undertake.

This heritage informs our approach to dredging — balancing the critical infrastructure needs of navigation and coastal protection with meticulous environmental monitoring and habitat preservation. It's not just how we do business. It's who we are.

What Sets Us Apart

24/7

Built for Continuous Operations

Dredging doesn't keep office hours. Our crews run around-the-clock operations with computer-tracked dredge positioning — the way federal and municipal marine work gets done.

220+

Combined Years

Our leadership and senior crew bring over two centuries of hands-on dredging experience — from the Gulf Coast to the Great Lakes, across USACE, state, and municipal contracts.

ECO

Environment First

Turbidity monitoring, seagrass avoidance, manatee observation, and turbidity barriers on every job. Environmental compliance isn't a checkbox — it's the foundation of how we operate.

Leadership

AGDM is led by its working principals — people who bid the job, run the job, and answer for the job. Full leadership bios and key-personnel résumés are provided with every proposal and on request.

Estimating & Project Delivery

Principal

Over 25 years of experience in dredging operations, equipment management, and marine logistics — operational knowledge that goes into every estimate, so AGDM's bids reflect how the work actually gets done on the water. Leads bidding and project delivery on federal and municipal dredging contracts from mobilization planning through closeout, across multiple simultaneous project sites throughout Florida.

Fleet & Field Operations

Principal

Over 25 years of continuous experience in heavy civil marine construction, quality control, and hydrographic surveying. Runs AGDM's cutter suction dredge and support vessel fleet in the field — hydraulic and mechanical dredging methods, computer-tracked dredge positioning, AutoCAD survey control, and environmental compliance across USACE, FDEP, and county protocols.

Marine Operations

Operations Lead

Over 20 years of experience in marine construction and dredging operations. Deep expertise in field execution, equipment operation, and project coordination across federal and municipal dredging contracts throughout Florida.

The Team Behind the Machine

Experience
Isn't Hired.
It's Built.

AGDM isn't carried by one or two people. Our senior field crew includes five operators and deckhands who each bring 30+ years of individual dredging experience — men who have run cutterheads, swung ladders, and laid pipe across every waterway condition Florida can throw at you.

Combined with our leadership team, that's over 220 years of dredging knowledge on every job site. When AGDM mobilizes, you're not getting a crew that's learning on the job — you're getting a team that's done it a thousand times before.
