Our general contractor was Nordic Custom Builders out of CT. They were fantastic to work with. Eamonn Ryan was our primary contact. Their subs were great, they got the job finished on time and on budget (the building, as you know, has many requirements), and were complimented by our architect, neighbors, and building management. I highly recommend them.
