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
"When we were planning our renovation project we wanted to partner with an organization that has a similar understanding and care for their customers. The decision to select Rosati was an easy one. The Rosati name carries a great reputation for experience, knowledge, quality, customer service and professionalism, which aligns perfectly with WFS' core values.."

Customer Experiences
"Their attention to detail was unbelievable. They worked really well with the architect, and real teamwork is required for that. They’re perfectionists, and I respect that. They sign their name to every job and they’re not going to do that unless it’s done right.."
