Our clients say

Michele R-I

Steel Company

We are a steel company located in Wilmington, DE and CNS provided audiometric testing and training for our HCP. The process was easy. They were able to knock out nearly 40 employees in no time at all. The pricing is transparent and very competitive. The onsite occupational nurses were terrific. We were able to get started addressing potential areas of concern right away with data on hand. I cannot speak highly enough about CNS.
