About Us

The importance of company history is to build a role in trust and respect, to our existing customers and to the customer that has yet to come along.

Every company is shaped with events that have taught us, inspired us, and gave us disappointment and courage.

We here at PS&C are no different. We have spent the last 20 years learning practices, growing in knowledge, and building a business that you have come to depend on. For this, we say “Thank You!” You the customer are the most important aspect of our business and without you we would not be the company we are today.

Many people have asked over the years how PS&C came into existence. Our story is quite entertaining and most importantly God blessed from the beginning.

Our History

Petroleum Service & Calibration, Inc. was founded in May of 2000.

With a meager beginning, we stepped out on faith and gave God full control of our business. True to his word, he blessed us and continues to do so daily.

Who are the owners and what do they offer me, the customer?

Jeffrey D. McCrary
Jean Jenkins-McCrary

Our owners have compiled years of experience in this industry and bring the knowledge of rules and regulations with a “fire” to stand behind their customers allowing them to be the front person in their tie between the state regulators and inspectors.

Jeff McCrary began building gas stations at the young age of 16 shoveling pea gravel on the construction side. His curiosity into the testing standards, in 1986, moved him yet again to further his career. Jeff’s knowledge of testing regulations, laws, rules and requirements has grown tremendously and tank owners depend on him on a daily basis. Jeff has served on boards and committees of writing and advising on regulations within NC and SC.

Jean McCrary brings to you the office knowledge and know-how to build a company where customers receive quality customer service. Her background in human resources and business administration allow a team of office support to be guided and built; making PS&C the place to work and build a custoer relation. Jean brings a “team” atmosphere to the table and allows our employees and customers to work as family!

Their expertise combine to offer our customers the most accurate up-to-date compliance answers to their questions.
