About Us

Evaluation that fosters positive change.

We help the helpers to be more effective, empowered and informed.

We evaluate world-bettering programs — in the fields of prevention, health promotion, education, and social services — to help them use research and evaluation to do the most for good. Our team’s decades of combined skills and on-the-ground experience offer our clients a range of methods to answer real-world questions. We provide comprehensive evaluation services (as well as targeted consulting) at community, state, and national levels.

We are a woman-owned small business.

How We Work

Our style is collaborative. We partner with our clients to craft and implement evaluation plans. We focus our energies on timely, accurate, actionable results that measurably benefit the communities our clients serve.

Our plans are responsive. Especially when you’re helping people, you must be agile. Goals change. Contexts change. We encourage rigorous, multi-method approaches that emphasize inclusiveness and a cultural fit.

Our products are shareable. We ally with our clients to ensure our work together engages stakeholders, fosters evaluation use, and inspires program improvement.

Our results are clear and actionable. We answer your key questions and help identify future directions. We take the details and weave them into a full rich story.
