    They Went Above and Beyond

    "As the region’s Parker dealer, Tri-State was the obvious choice to work with on my new purchase. It was a great experience working with Tri-State and I would definitely recommend them to family and friends. There is only one word to describe Ron Young and that is “Awesome”. He’s just awesome at what he does and he is a genuinely good person. Everything went smoothly and he left no stone unturned when it came to making sure that my experience was positive."

    They Treat Me Like Family

    "All of my boats have been great and what keeps me returning to Tri-State is the staff. You're treated like family - there is no desire to negotiate because you are confident they are giving you the best price and are always honest. From the Sales Team, the guys in the shop working on the boats to Dawn at the Marina, they are all so helpful and that is the reason I continue to come back."

    Top Notch

    "The folks at Tri-State Marine are top notch! I recently purchased my first (new) boat and they were incredibly patient with me, as this was a big decision. I was on the fence about another boat and they made it very clear that they wanted me to be happy, as opposed to the “sale”. Ron, my sales representative was outstanding and always responsive. They have earned my business and support for many years!"
