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
"Since the early 1990's, we have worked together on several different projects beginning with the conception of the Ford Windsor Aluminum Plant many years ago through the construction of multiple projects. From Minor renovations to full-scale construction, we have found you and your staff to consistently meet our high standards of quality and on-time completion.."

Customer Experiences
"Rosati is a quality bunch of guys. They know their stuff. They know our industry,” said Circle 5 co-owner Keith Lavergne. “Hiring Rosati saved us from going to several sources to get several parts of the project done ourselves. Rosati is truly a one-stop shop for industrial expansions and machine foundations. Everything’s on schedule and within budget. Rosati is a good company to work with."

"Rosati is a great group of professionals, very thorough, very accommodating and accountable. I am happy with the finish of the office and everyone who has toured it so far has been extremely impressed. Multiple people have asked "who built this for you?"."
