..reveals opportunities for improvement
“Laura has learned the workings in IFCB and has begun taking on the tasks I’d expect of an Executive Director such as leading strategic planning with significant involvement from board and staff, improving our financial reporting, making fixes to our budget, and sorting through staffing issues that should help to strengthen teamwork. She asks questions in a non-threatening manner that shows respect but that also reveals opportunities for improvement.”

We benefited from an ambitious timeline…
“We were so pleased with the outcome of our work together with the right people who bring exactly what we need to grow our team. But what stands out even more is the process. We benefited from an ambitious timeline that we were able to stick to.
The team listened carefully to understand our organizational goals, culture, and how these positions fit in. And we had several candidates show up to in person interviews telling us how much they enjoyed and appreciated the personal interview. This is what any organization would hope to hear about the consultant acting on their behalf!”

Director of Programs and Finance
…marveled at their level of insight.
“Christine her team did a fantastic job for our fledgling non-profit- they listened to what we needed, helped us craft the right job description, put together a posting that attracted far more candidates than our prior efforts, and then-best of all-did a careful and thoughtful job interviewing the candidates and narrowing the field. I learned a lot working with them and marveled at the level of their insight-it really helped us land someone *much more likely to succeed with our mission and work well with our three founders than we would have done otherwise! I would work with them again in a heartbeat – my highest recommendation.”
