Rosati Difference
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
"It was a no brainer to approach Rosati, after having such a great experience with our first new build in Windsor, Rosati's turnkey approach to construction saved us time and money. They helped us source the right land, design the building and ultimately built our new facility. The facility with Rosati’s quality touch will allow us to continue to grow and contribute back to the community of Chatham-Kent. Rosati provided us with options for changes that somehow find the rare combination of achieving our request and staying within a reasonable budget. They don’t put forward just one solution; a spectrum of options allows us to make better decisions to balance design and budget. Rosati’s work is top notch and their ability to manage a project – from design, to paperwork, to construction – is among the best we see across the country. ."

Customer Experiences
"We have worked with Rosati before. They have tremendous attention to detail and stick to their timelines, something we were concerned about. We had a firm deadline when we had to be out of our previous office. Rosati knew that and went the extra mile to make sure we had no issues. They did a very good job. Every day when I walk through the doors, I'm happy. Even more importantly, staff members are very happy.."

"Rosati was not only the most competitive bid, but they are also proven performers. They are very thorough, and very good with respect to managing their projects. They give advice where advice is needed, and we have leaned on their expertise for a lot of decisions.."
