She combines 20 years of industry knowledge and experience conducting software quality assurance with the Department of Defense, building engineering design in the Pacific Northwest, renewable energy planning at Hawaiian Electric Company, energy efficiency and conservation at Puget Sound Energy (PSE), and management of PSE's Transmission Engineering Department. She led HDR’s Washington Power Delivery Substation, Transmission, and Distribution Engineering teams, where she was responsible for strategic business development and growth, client services, and employee development and performance.

Jennifer was on PSE’s Women in Leadership Planning, Training, and Mentoring committees, where she was a Strategic Agility Trainer and Presenter. She is a 2018 graduate and 2019 coach of Leadership Tomorrow, a civic leadership program in the Puget Sound region.

At PNNL, Jennifer leverages her deep expertise in DEI and industry experience to develop equitable and community-centered approaches to energy systems planning.

She also provides strategic support for initiatives bringing energy improvements to rural and remote areas.
