Why I belong to the National Drilling Association:

"NDA member Tom Brown hired us for a large job in DC and Connelly & Assoc., also an NDA member, provided us a licensed driller for a job we had in Delaware. (We had lost the services of our NY/NJ/DE licensed driller to a stroke.) In addition I have quoted a couple large jobs to Jim Howe of Geotechnology that haven't materialized, but we've been trying to team. We also sold a truck to Geotechnology. So it's not just a meeting of peers-being a member of NDA offers promotion of the Geotechnical and Environmental drilling industry as well as teaming or prime/sub opportunities with other member firms."
