What is an environmental technician? An environmental technician is a professional that needs to wear many hats and know about conditions that could impact the occupants in the home. Our technician George has been trained to help you and your family test for mold, radon and the water quality in your home. Technicians need to be self motivated and incredibly organized to be able to run multiple tests simultaneously for families and George is able to do that with ease. If you see George at your home ask him about his hobbies and he will talk your ear off over the many beautiful golf courses he has played over the years.
