Why I belong to the National Drilling Association:

"NDA is more than an Industry Association. It is a real community of geotechnical and environmental drilling professionals. It has been my experience that the biggest single benefit our company has received from being associated with NDA has been the opportunity to collaborate directly with members for the exchange of ideas and the development of safety programs, training and to improve our industry standards. In addition, we have obtained new clients, and new projects which have stemmed directly from the NDA’s web site. We have developed working relationships with all of the members of The Mid-Atlantic Chapter and some national members of the NDA as well. It is hard to put a value on such a network or an organization."
