Mary Hensley, President and Director of Marketing
Mary knows her customers are busy running major manufacturing facilities, businesses, hospitals, and universities. As Director of Marketing, it is her primary focus to make sure that Enspire offers a competitive suite of natural gas products and services that allow our customers to do what they do best, while not having to worry about the complexities of their natural gas supply and costs.
Mary is one of the founding partners of Enspire Energy and has over 17 years of direct experience providing natural gas supply and service to industrial and governmental accounts in the Mid-Atlantic region.
FULL BIOGRAPHY
She started her career at Pepco Energy Services, moving from a marketing analyst, to gas scheduling, where she handled nominations and balancing for industrial accounts behind 17 different LDCs and pipelines, and eventually being promoted to a regional account manager, handling sales of natural gas supply to industrial and governmental accounts in the Mid-Atlantic region.
Mary then accepted a position as the Manager of Business Development at Compass Energy, where she helped to expand their customer base behind Virginia Natural Gas and Columbia Gas of Virginia. Since Compass was a smaller organization, she received first-hand knowledge of all aspects of the gas business from buying and selling supply, arranging transportation, and invoicing.
In 2005, Mary left Compass Energy to be one of the founding partners of Enspire Energy. Enspire Energy quickly grew to be one of the largest natural gas suppliers in Virginia, serving several Fortune 500 companies as well as industrial and governmental entities. In 2009, Enspire Energy was sold to Shell Energy North America, and Mary joined the natural gas sales team at Shell. Mary was responsible for natural gas sales to large industrial accounts, including to the federal government. She worked closely with trading to price out long-term competitive natural gas supply in the Mid-Atlantic region, while also handling complex contract negotiations and approvals.
In 2013, Mary left Shell to work on re-launching Enspire Energy. With the number of acquisitions and mergers in the natural gas supplier marketplace, Mary felt that the market was asking for a more local approach to natural gas supply. With the successful re-launch of Enspire Energy in October 2014, Mary is thrilled to be able to offer large commercial, industrial, and governmental accounts a new choice for natural gas supply in the Mid-Atlantic region.
Mary is the proud mom of two boys, and enjoys volunteering in her community as well as travelling and scuba diving in her free time.
