Who We Are

Fidelium Consulting provides government and corporate clients with an agile small business partner for developing and managing high-performing market engagement programs. Our founding Principal has helped U.S. federal agencies accelerate the adoption of proven decarbonization, energy and water efficiency, and waste reduction approaches for nearly 15 years—work that has never been more relevant. As a smaller firm, we can apply the lessons learned through this experience in a customized way to help your organization achieve its programmatic goals.

Meet the Principal

Zach Abrams

My mission is to accelerate positive change by helping forward-thinking public and private organizations partner together better. Over a 12-year career at ICF, I acted as a trusted advisor to dozens of federal staff, and over 100 corporations, local governments, schools, and non-profits. I learned the value of being responsive and collegial, identifying collaborator priorities and constraints, and helping create a roadmap to achieve their goals. Fidelium Consulting embodies these principles making it a trusted advisor to our clients, a valued asset to our teaming partners, and a fantastic workplace for our employees.
