DSA takes pride in exceeding expectations with a unique approach of mobilizing our highly experienced supervisors with a tool box loaded for the most demanding of scenarios. Time spent waiting for a tool is costly time not in production. DSA employs a competent and experienced staff which has embraced the philosophy of DSA. Like many successful independent companies DSA was founded by an individual with a unique drive and passion to provide unsurpassed thru-tubing solutions. He has instilled a simple and tangible work philosophy he calls TLC (Total Lowest Costs) into each and every employee at DSA. TLC is what has allowed DSA to grow and achieve an unmatched record of success that we continue to share with our customers since DSA’s formation in 1986. DSA is also very proud of its spotless safety record and ensures each employee is ready to perform his/her work in a safe and environmental friendly manner through appropriate training and tools to do their job.
