Marina development company testimonials quote
After 15 years and 7 start-to-finish projects with MDI, there is no need to consider engaging anyone else. They do exactly what they say and more; their docks are impeccable, their response time is immediate and their crew is top-shelf. They take care of everything turn-key, so I can run my business.

Our docks required special ADA accessible ramps and walkways, plus expandable slips for boats 100 feet and over. MDI did it all, as planned and as promised.
