As a Colorado native, Steve grew up just outside of Denver where he attended Cherry Creek High School. He is a graduate of Regis University as well as the University of Wyoming, where he met Kathleen. Steve and his family now happily live in South Denver, with the newest addition to their family, Gracie, a golden retriever puppy.


When we founded RadonRelief in 2007, we were one of just a handful of radon mitigation companies located along the front range. While now there are hundreds of companies to choose from, we would like to think that you would choose us to work with because we care. Not only do we provide the highest quality work, products, and service, but we do so with honesty and integrity. We aim to get it right the first time and if we don’t, we’ll keep trying until we do.

We look forward to working with you.
