Our Founding Story


  It all started with a high radon test in a home Dawn Coffee was selling.  After learning the home she was living in for 5 years had dangerous radon levels the same equivalent to smoking 40 cigarettes a day, Dawn began her pursuit to learn everything she could about radon.  With 12 years experience in the home inspection industry Dawn launched an environmental testing company of her own.  In 2015 the business grew to a level where her husband Bob could leave his management position in real estate to join Dawn and build their company together.  Shortly after, they acquired Valley Lea Laboratories in Mishawaka and merged the companies to form Your Environmental Services LLC, (aka YES) a full service clean air and clean water company with two locations in Mishawaka and now Fort Wayne, Indiana.   The heart of Bob and Dawn's passion is to help educate people about air and water quality in homes and buildings through environmental testing and recommending realistic solutions when needed. The team at YES focuses on creating environmentally healthy homes while making a difference in the community and the world around them.
