Rosati Difference
Customer Experiences
"Our experience with Rosati has been outstanding. Denis and Nick have kept us completely informed of the progress, in detail, throughout the project. They went out of their way to provide options and creative solutions for decisions that had to be made along the way.."

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.."

Customer Experiences
"Rosati’s design-build expertise allowed them to take my ideas and put them on paper from a concept and then to a master plan. During any renovation there are always surprises, and this project was no different. When there was an issue, Rosati would tackle it right away, not only with what the problem was but also showing us different options on how to fix it with minimal delays.."
