My role is to implement processes that shape project development efficiently, respectfully, and successfully. While ensuring projects are developed well, I advance the combination of attention-to-detail organization with big-picture planning. I've worked on both project development and project finance teams at Cypress Creek Renewables, Sol Systems, and Summit Ridge Energy before joining the Onyx team. I've managed and financed utility-scale, community solar, DG, and C&I assets. I currently serve on the Executive Team of EcoWomen's National Board, a nonprofit that works to inspire and empower female leaders in sustainability. Education: B.A., Urban Planning & Public Policy, University of Illinois at Chicago M.P.A., with distinction, DePaul University
