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.."

"This is our first time working with Rosati. With their strong LaSalle presence and their amazing reputation, we felt it was a great opportunity to work with them. We couldn't be more proud of the product they put out. This is different from our other properties; it's a new concept for us and definitely unique. Without a doubt we would work with Rosati again.."

"Autoliv chose to work with Rosati Construction due to their ability to manage a project with the highest degree of attention to detail. It has always been our experience that Rosati construction leaves nothing to chance and ensures that schedules are maintained through tireless follow up and continuous communication with the customer. As "change" is an inevitable component of any large project, Rosati approaches changes in stride and shows a high level of flexibility in reacting to them.."

"After about seven projects with Rosati, we have a long-standing relationship. They are very thorough, and they definitely understand our business needs and are good at coming up with solutions for us. Rosati was very responsive in completing our building design, since we had a very tight timeline to work with. We are very satisfied with their delivery of projects, for sure.."
