Ultimately, we felt the Rosati Group offered us the best value and was the right company to partner with for our pharmaceutical expansion project. We are very pleased with Rosati's attention to detail and overall project management approach.."

"From the design phase through construction, and even now in the maintenance phase, Rosati has gone above and beyond our expectations. Rosati most competently got our project completed when we needed it. Rosati’s attention to detail complemented our own perfectionist tendencies. We would highly recommend Rosati and are very happy that we chose them for our project."

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.."
