Jarrett said: As always professor, you made this engaging enough to stay focused and never lose steam but also educational enough to always feel like what's being discussed is MUST have information in our field. I've called you on the phone before and you've helped me in the few times I've been in a jam in the field. To know that you're not doing this for just money, but for the overall betterment of us radon professionals to make sure clients and customers understand and can trust the results we provide means the world to me. Thanks!
