Our Story

It started with

Steve Zimmerman

He founded Spectrum in 2007 with the strong belief that nonprofit organizations are the force for change in many communities. To sustain such crucial impact, Steve helped write the book on sustainability, joining other leaders in recognizing the inseparability of a nonprofit's mission from its finances.

Since then, we've grown our team and our expertise to more effectively tackle strategic challenges confronting nonprofit leaders. But our mission has remained the same: to strengthen yours.

Our pillars


We use our knowledge and tools to break down the intricacies of nonprofit management and finance to engage your whole team around strategic challenges. By listening to your goals and priorities, and earning your trust throughout our process, we build lasting relationships that lead to greater success in implementation.


Sustainability is an orientation, not a destination. It’s the choices that you make day in and day out that will allow your organization to have impact in a financially viable way. We respect where your organization has been but also help you see what it can become.


Nonprofits today can’t afford to think about strategy once every five years. They need flexible strategic models that are meant to adapt to the inevitable bumps in the road. We’re strategic problem-solvers, helping you balance internal demands and external pressures.


There’s no one solution to sustainability, so we work together to find an answer for you. We equip your organization with the ability to involve everyone, from the program assistant to the board chair, ensuring that you have the knowledge and skills to own your strategy.
