NorthStar Environmental Testing, LLC (NorthStar) was established in 2009 to provide a cost effective environmental consulting option for the Central Wisconsin area. As we have grown, we have had the pleasure to assist commercial, industrial, and residential customers throughout Wisconsin and neighboring states with their environmental testing and inspection needs.


In order to continue to meet the needs of our clients, NorthStar continues to grow  with the addition of a Fox Cities office in Appleton, Wisconsin and office in Madison, Wisconsin. We feel it is extremely important to provide a local contact and immediate response capability should the need arise for any of our clients.


NorthStar’s staff brings a combined 40 years of experience in the environmental consulting, health/safety, and industrial hygiene fields. We appreciate all the relationships we have built in the past, and are hopeful we can continue to build these relationships well into the future. We here at NorthStar will strive to meet and exceed all customer expectations while keeping customer costs as reasonable as possible. Click here to meet the NorthStar Team.
