Focused on delivering extraordinary results

The work we do on behalf of our clients is often the first of its kind, largest of its kind, goals-exceeding, barrier-overcoming, and bar-raising, ensuring we deliver pioneering solutions. We’ve helped our clients achieve honors for outstanding results from top industry organizations, including the Association of Energy Service Professionals, the National Association of Government Communicators, CDP, and the American Institute of Architects.

This commitment to achievement is the reason Cadmus’ expertise is sought by a diverse list of federal, state and local agencies; why most major utilities have engaged our services; and why Fortune 500 companies regularly reach out for our help.

Meet the experts who can help you achieve the extraordinary

No one achieves the extraordinary with pre-packaged solutions or silo-based thinking, so at Cadmus we attract the most experienced, knowledgeable, and creative talent. We’re passionate about working across disciplines to define the best possible approach to your specific challenges and reach transformative outcomes. No matter what our role is on your project, you can always be sure that your mission is our top priority.

When we discover great people, we invite them in

We believe that joining forces with talented people and organizations helps us constantly innovate to meet our clients’ evolving needs. For example, when we acquired Quantec, we expanded our energy efficiency and renewable energy expertise; and with Obsidian Analysis, we offer best-in-class security and resilience experience. When we acquired ifok and Meister Consultants Group, we grew our capabilities in change management, sustainability policy, and stakeholder engagement. We further enhanced our European offerings with the acquisition of RaikeSchwertner, a full-service agency specializing in the strategic communication of complex topics and products, with a particular focus on sociopolitical and economic transformation processes. When we acquired Wheelhouse Group, we significantly expanded our change management capabilities especially in the IT modernization, citizen services, and workforce transformation spaces. Most recently, we increased our global presence and impact with the acquisition of Nathan Associates, Inc., integrating their longstanding international development technical expertise and financial advisory services. We continually seek additional partners to help our clients achieve extraordinary results across many sectors.
