The Meaning Behind The Rings

Michael Conrad, President of the NSA, says, “You’ll notice on the right side of our logo, the separated rings represent a typical relationship between Building Service Contractors and their chosen suppliers. As these rings move to the left, they are in complete alignment, which is our goal to bring our members and partners together creating a cohesive partnership that delivers industry best value. We are thrilled with the new look of NSA and extremely excited about the future”.
