Rosati Difference


Customer Experiences
"Rosati was excellent to work with and, in partnership with ADA and WFCU, brought the project in on time and slightly below budget. WFCU would not hesitate to work with Rosati again under the proper set of circumstances, nor hesitate to recommend them to others. They made the entire project experience smooth and successful.."

President and CEO


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.."
Jonathan Reaume
Owner/Chef


Customer Experiences
"Rosati has been a tremendous help. I’m so happy I went this way, It was just so easy. Other people have to be on top of their builders, but it’s pretty much been the opposite with Rosati. They’ve been great at keeping on top of things and meeting the timelines.."

Customer Experiences
"We were very impressed with the quality of work on Phase I, and that Rosati was able to meet our tight timeline. This was important because some of the practitioners were just starting their practices. Rosati delivered, and we were impressed. There was no question we wanted to work with them again on Phase II.."
