I cannot imagine being in the NDT industry and not having the camaraderie and friendship of the literally hundreds of NDT professionals I have grown to know while volunteering with ASNT. I cherish that more than the employment itself. The employment pays better, but a dollar value cannot be placed on the rewards of being part of ASNT.”
