About Us





Established in 2007, Athelon Enterprises, LLC is locally owned and operated by Daniel Hylland.  After a family member was diagnosed with lung cancer, Daniel started learning about radon, and how important it is to eliminate this health risk.  Daniel decided to take action and start testing and mitigating homes for other people. 


He received radon testing and mitigation training from Midwest Universities Radon Consortium, which is sponsored by the University of Minnesota Extension Service.  In addition, Daniel is certified by the National Radon Proficiency Program and is listed with the Minnesota Department of Health.


Daniel handles the design and installation of all radon mitigation systems and has personally installed thousands of systems.  He is a licensed residential contractor with over 14 years of residential construction experience and over 10 years experience as a licensed real estate agent with Keller Williams Premier Realty of Rochester.  He takes pride in his work and strives for 100% customer satisfaction.
