Cassie Mullen photoCassie Mullen began her career with St. Louis-based petroleum equipment company Neumayer Equipment. Over eight years she learned every aspect of the business and rose to Director of Sales and Marketing. She then became an owner/operator of a retail convenience store in Kansas City, eventually growing that portfolio to include four branded retail units.
She also served as the Business Development manager for PB Hoidale and created the Petroleum Safety Council in response to the ABC UST Operator Training required by the federal energy bill of 2005. Her curriculum was ultimately adopted and approved by Colorado, Utah and Iowa. It was during this time that she developed a passion for renewable energy. She has lobbied state and local officials on behalf of the industry and worked with Dresser Wayne on the design and manufacturing of the first ever blender dispenser brought to market.
Most recently, Cassie was a Strategic Account Manager with Seneca Companies, a provider of petroleum storage and dispensing systems, vehicle service equipment, fuel site construction, environmental services and remediation systems. She was responsible for a territory of more than 13 states.

She has extensive experience with fuel infrastructure design build, service, construction, liquid handling environmental requirements, and local and federal liquid handling regulations. Importantly, her knowledge of major oil branding is a critical component of her success. She has been involved in the Petroleum Equipment Institute serving as a past board member, longtime member of the PEI Young Executives, and more recently the Women of PEI.
