  21. Jarrett

    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!

  29. Tom

    *As a provider of residential radon measurements, I took this out of curiosity. The multi-family word is tremendously different and this provided a great overview of that.

    Excellent course for any measurement specialist. Wish it would it had been available earlier in my career.

  51. Gary

    Good CE class

  52. Stan

    I think the course quality is excellent. I think it could be improved if you had video of testing being performed in the field (perhaps with Eperms?) to help students better conceptualize and apply what they have learned!

  53. Ryan

    learned a lot

  54. Dustin


  55. Vicki

    Very comprehensive and great reference materials

  56. Stephen

    Interesting information. Good overall protocol review for any tester. But not a necessary course unless you intend to do multi-famliy. Multi-famly looks like a big undertaking, and not for the home inspector who does single radon testing on his own inspections..

  57. Nathan

    I recommend this course

  58. Jason

    one of the better CE courses I have been thru.

  59. Paul

    Very knowledgable instructors and relevant materials…should help my business as I learned lots of new things.

  68. Billy

    Very good class

  69. George

    Thannk you for the useful information

  70. Therese

    Very straightforward.

  71. William

    The course was informative. I do have some issues with several of the quiz questions. Some unstated assumptions were used, and additionally, one question from quiz one contradicts a question from quiz two with regard to acceptable RPE. (quiz one question 1 and quiz two question 24)

    The answer to the question: “According to the MAMF-2012, if an apartment complex has 6 separate buildings with 15 testable locations in each building and the building needs to be tested quickly pending a real estate transaction, how many individual devices will be needed?” does not include devices used for QC. I believe one could reasonably argue that answering ‘false’ to the question: “The results of blank measurements should be less than 2.5 pCi/L.” is more incorrect than answering ‘true’.

  72. Lindsay

    I recommend this course

  73. Judy

    Great course. Every radon professional should take this course. Judy O’Loughllin, Air Chek, Inc

    It seems that this course should have been worth more than 8 credit hrs. As compared to other courses I’ve taken. There was ALOT to it. Good course though.
