Our Network of Nonprofit Interim Executives

Interim Executive Solutions has developed a network of highly accomplished professionals with experience leading both nonprofit and for profit organizations. Our Associates bring general expertise in key areas such as assessing organizational needs, determining and acting on priorities, developing the capacity of staff, communicating with stakeholders, and collaborating with nonprofit boards on vision, strategy and future leadership needs.

In addition, many of our Associates have deeper expertise in particular practice areas such as finance, fund-raising, human capital, systems and operations, technology, public relations, and the law, and they are willing share their knowledge in these areas when needed by others.

Here we highlight just a few of the Associates currently available in our network:
