As award-winning researchers and consultants, they lead a national team of experts and partners who are strongly committed to excellence, authenticity, and responsiveness. Together, their customized approach has won the company more than five awards in sectors from education, to government, to business.

Don’t just take our word for it

“In an ideal world, every social change not for profit organization can benefit from the objectivity and insight that Osa brings. She thinks outside of the box while considering both macro and micro viewpoints as was illustrated by her capacity to simultaneously address both our stakeholders' needs and our organization’s needs. Her ideas and innovative solutions were always in alignment with the mission of our organization. And she has an innate understanding of initiatives that work for social change.I can highly recommend Assemblage’s work as a consultant for not for profit organizations,particularly organisations that are engaged in social change.”
Jac O’Keeffe
President and Co-Founder
“Throughout our project, it was evident that the Assemblage team understood the needs of foundations and was committed to helping Girl Up improve our ability to execute our mission. I was impressed by the excellent standards of our Assemblage project managers—especially their willingness to solicit feedback and understand our goals. We’ve already been able to incorporate recommendations from our evaluation into our campaign strategy and see the direct impact of our project together.”
Julie Willig
Senior Grassroots Officer, United Nations Foundation, Girl Up
“Huge thanks to Dr. Osa Adajan and the Assemblage Advisement and Consulting team for your amazing work this year! We really appreciated your collaboration as we built out the Reboot work. We have greatly valued the level of professionalism and wise perspective you have brought to this work. In addition to your deep expertise, we have genuinely enjoyed working with you and the Assemblage team.”
Celeste Jalbert
Former Senior Director, Programs, Reboot Representation
“Assemblage Advisement and Consulting really took the time to understand both our goals and the realities we would face in trying to achieve them. My previous experience with external evaluators had been a real struggle with an unwillingness on their part to make things work for the people involved in the program being evaluated and within a specified budget. In contrast, Dr. Adajan and his team have prioritized the people involved, set out a reasonable and achievable plan and taken enormous pressure off of me as a project director. They also embrace that fact that “things change” and have provided the kind of flexibility that my projects have required.”
