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 zero environmental incidents — every single time.
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.
AGDM is a Native American-owned enterprise. Principal Joey Walsh 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.
Every project delivered on schedule and within budget. No exceptions. No excuses. Our track record speaks for itself across federal and municipal contracts.
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.
Zero turbidity violations. Zero seagrass impacts. Zero regulatory actions. Environmental compliance isn't a checkbox — it's the foundation of how we operate.
Over 25 years of continuous experience in heavy civil marine construction, quality control, and hydrographic surveying. Specialist in bidding and executing multi-million-dollar federal and municipal dredging contracts. Expert in hydraulic and mechanical dredging methodologies, AutoCAD survey plotting, dredge computer positioning, and environmental regulatory compliance across USACE, FDEP, and county protocols.
Over 25 years of experience in dredging operations, equipment management, and marine logistics. Oversees fleet maintenance, mobilization planning, and field operations for AGDM's cutter suction dredge and support vessel fleet across multiple simultaneous project sites throughout Florida.
Over 20 years of experience in marine construction and dredging operations. Brings deep expertise in field execution, equipment operation, and project coordination across federal and municipal dredging contracts throughout Florida.
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.
Aidyn grew up on the water and on the job. His spirit is part of everything we do at AGDM — and he is deeply missed by everyone who knew him.
