Rosati Difference
Customer Experiences
"We had gone through local knowledge and the Rosati name kept coming up. When we contracted them, they were very responsive, very knowledgeable and flexible. They showed us the history of what they have done in Windsor and it was extremely impressive. We were also very impressed by the speed with which they could get things done. I can’t say enough good things about Rosati. They work quickly, diligently and effectively, always with the budget in mind. And since they really do have many in-house capabilities, they can move quicker than any other construction team we have ever worked with. We are very satisfied with the work so far.."

Customer Experiences
"Our family-run business Manz Contracting is no stranger to the Rosati family. We are proud to have cultivated a long-lasting relationship with the Rosati’s, starting with founders Vince and Olivia nearly four decades ago. The key to success has always been to service your customers and build quality projects on time and within budget. This is why our family group at Lakeshore MedArts investigated several contractors. We feel we have picked the premiere local contracting firm in Rosati to build our facility, following the same tradition we will continue in our future business endeavors. It's actually been a lot of fun and it's been great to work with Rosati. They have always responded to everything we needed in a very timely fashion. Things can go south really quickly if you don't have the right people. We give kudos to the people at Rosati.."

Customer Experiences
"We picked Roasti because they are tremendously experienced. Besides the advantage of working with a local contractor, they build awesome buildings and bring a level of detail that is hard to find. We were trying to customize every detail and we found a contractor with the same beliefs. The team we were privileged to work with has been instrumental in making the project as awesome as it turned out.."
