With a background in finance and management, after 20 years of helping run and grow our successful family plumbing business, I decided I wanted my own company. I wanted a company that I could be passionate about and one that would make a difference. Lung cancer prevention and education struck a very personal chord with me, so I decided to start a radon testing and mitigation company. Meeting Steve Shaw, the previous owner of Reliant Radon Solutions, who was ready to retire, made things fall into place. I’m dedicated to excellent customer service and to doing things the correct way. The staff at Reliant Radon are all top-notch and also dedicated to being the best in this business. We’re focused on saving lives, not just turning a dollar.
