Harbor Cove Management was founded by Mike and Geri D’Agostino in 2000. Their grown children Dan & Lea, daughter-in-law Kristen, Elisa and Haley are also part of this family owned and run business.

As boaters, Mike and Geri started coming to New Buffalo in 1992 and purchased a second home in the harbor. They moved here permanently from the Chicago area in 1999.

Harbor Cove has been involved with million dollar + building reconstruction projects, dredging of boat slips and fairways, rebuilding of private roads, construction of landscape walls and seawalls and many other projects both large and small. They have knowledge and experience in many facets of this business.

Geri and Elisa are also licensed realtors with Keller Williams Southwest Michigan in New Buffalo and can help with the buying or selling of your home or boat slip. They can also assist you with a seasonal boat slip rental in the New Buffalo harbor, either as the slip owner seeking a renter or as the renter seeking a slip for the season.


Dan D’Agostino is Harbor Coves Maintenance Supervisor and also a sales associate with Basa’s Marine at their New Buffalo location and is very knowledgeable with all aspects of boating.  Therefore, if you are in the market to buy or sell a new or used boat, looking for a slip to dock or store your boat, need a used jet dock or lift for your vessel, or anything revolving around the marina – keep Dan in mind!
