Why I belong to the National Drilling Association:

"I was a member of the NDA for the past 26 years through my former employer, and always enjoyed the many resources of the NDA, such as safety hits, tailgate talks and references. Now that I am the owner of my drilling company, I find that membership in the NDA is one of my company's most valuable assets. By being an NDA member, I feel confident that if I have a question or concern related to the drilling industry, help is just a click or phone call away! Having just returned from the NDA drilling convention at Seven Springs, I just wanted to say that it was terrific, filled with interesting seminars and great information about the current trends in the industry. It also gave me a chance to reconnect with colleagues, vendors, and friends in the industry. Thanks for all you do!"
