Charlie, based in Cleveland, brings extensive technical experience and a keen humanitarian perspective to Go. Charlie helps ground our conversations and our focus on the real-world impacts of our projects and our client’s choices.


Charlie’s data organization and analytics skills allow him to lead large-scale utility data analytics projects to perform third-party benchmarking, tracking, and measurement and verification (M&V) services for our utility and portfolio clients. His investigation skills allow him to bridge understanding with our clients seeking to better understand their choices within energy regulatory and policy realm and how these will impact their organization, constituents, members, and other stakeholders. His knowledge of the broader electrical grid locally, regionally, and nationally allows him to deftly assist our clients in navigating their efficiency and generation technology choices, especially when these choices beget complex grid-scale economic ramifications.


Charlie has a critical and forward-thinking mind, constantly focused on society’s path towards decarbonization and electrification, which results in him frequently leading our team in complex and novel projects. He has supported a major transit system’s long-term decarbonization plan focused on bus fleet electrification. He leads discussions with clients on the resilience, equity, and economic reasons for focusing on microgrids that combine renewable energy and storage. He has been the architect of developing unique methods of comparing large-scale portfolio energy data. Increasingly, he contributes this collection of knowledge and experience to regulatory discussions through analysis and research to support policy and regulations across multiple states.


Charlie received his Bachelor of Mechanical Engineering and Master of Science in Mechanical Engineering from the University of Dayton. While at UD, he served as a student administrator for ETHOS, a community engagement and experiential learning program that sends undergraduate engineers to work on technological solutions in developing countries.


Charlie’s creativity extends beyond the novel and complex energy challenges of our clients, and you may find him woodworking, gardening, and occasionally carving snow. He also enjoys hiking and exploring the many parks of the greater Cleveland area.
