  15. Don

    It’s nice to be able to do these on line, even for a 83 year old guy that’s a little behind on computer skills.

    You need to sort out the people that have building experience and people who have no on the job experience.

    You do a good job of that.

  31. John

    The course was excellent as usual. I have been taking training courses from Mr. Kladder since 1995 when he was with the WRRTC. He has acquired more knowledge as have I over the years. He has always developed, produced, and presented material in a manner that is easy to comprehend and remember. 

    The discussion of the material by attendees yields valuable information just as it always has. I recommend CERTI to everyone I know in the radon business and contractors who plan to build structures that are radon resistant.
