Rosati Difference
Customer Experiences
"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.."

Customer Experiences
"Rosati Construction was selected based on their reputation to meet budget and timing. Their group's ability in all areas of the project, resulting in the completion of out 72,000 sq ft. facility to house our North American technical centre and headquarters in under six months. I believe this to be an impressive accomplishment by any measure.."

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.."

"The Rosati Group was extremely efficient in what they did. Based on their quality workmanship, follow-up and their attention to detail, they are getting more opportunities to bid on our work and are now completing another store in Windsor for us. It made my life a lot easier. I look forward to working with them again.."
