About 15 years ago, I was contracted to be the qualifier for a prospective Colorado well drilling company. Once licensed, I would have been acting president of the drilling company until the owners could qualify to get their own license.
I qualified for all the Colorado driller’s license requirements and then flew to Colorado to pass a required verbal examination in front of the licensing board. I believe this board consisted of one well drilling contractor, a pump installer, a plumber, three regulators and others.
