Jeffrey D. McCrary

Previous Owner / VP Operations

From 1984 he began building gas stations at the young age of 16; shoveling pea gravel on construction sites. His curiosity into the testing standards in 1986 moved him yet again to further his UST testing career. Once again in the 1990’s he found another great leap into the management of a UST company. These skills are what have made PS&C a company he is proud to call his own.

Jeff’s knowledge of testing regulations, laws, rules and requirements have brought tremendous customer relations and outcomes to tank owners during state inspections and also in their own personal growth and knowledge of what is required by them. Jeff is always willing to go the extra mile for his customers in ensuring they are not paying for un-needed or required services.

Jeff is co-owner of PS&C, along with his wife Jean McCrary and together they have built PS&C to be a company of integrity and top notch customer service for 20 years!

Zachary S. Elliott

General Manager

Zach was born and raised in the Lake Norman, NC Area where PS&C is located. He attended and graduated from a local high school and then attended college where he played one year of collegiate football. After a few additional semesters he decided to pursue a career in law enforcement. However, due to an unforeseen hiring freeze, he began searching for jobs in other field. In 2008, he met Jeff and Jean McCrary.

At that time, he joined the PS&C team as an in-field technician, and after 10 years of running the roads and learning all he could, he was moved into the office to become the Technician Supervisor. With his experience in the industry and the leadership skills he developed as a quarterback, he provides our technicians with the guidance and training they need in order to provide customers with the excellent service they deserve.
