Tom was extremely professional and most importantly very knowledgeable about the many makes and models available for my needs. Once we zeroed in on a boat he made the entire process effortless for me. I will strongly recommend the Dunigan Marine group to others.

We worked with Joe and Tom and they were able to sell our boat for a price that worked for us! Both of their communication was excellent! Joe created a great advertisement for our boat and was able to find a buyer and close the deal!

Tom is a very nice guy, he came recommended from my local marina. Another friend at a different marina was given Tom’s name as well. It is apparent he is a very busy person but he always responds in a timely manner.

Tom is awesome! He is knowledgeable and very personable. When it comes to boats and making the right decision he is your guy. Buying my first boat I didn’t know what to expect but Tom made the process as easy as one couldn’t imagine.

The sale of our boat was final yesterday. Thank you Tom Dunigan for leading us through this without any problems. Sure, we got a few low-ball offers but the right buyer came along.

Tommy was amazing in not only helping me purchase my next boat but also selling my other boat. Yacht brokers state they are family-oriented and have friendly service, but Dunigan Marine Group is by far the best and friendliest.

Tom is fantastic! I had not only hired him when I first purchased my boat to make me feel more comfortable and confidant in operating a larger vessel, I also utilized him when recently listing my boat for sale. Tom is honest, transparent.

Hands down, the best experience I’ve ever had. I contacted several boat brokers prior to finding Tom. They either never returned my message or would say they were too busy. Tom was different from the very start.

Tom Dunigan, exceeded my expectations. He sold my boat in less than 30 days. It probably could have happen quicker if not for me dragging my feet. He is knowledgeable about boating and puts an excellent marketing package together.
