Client Feedback

“I really appreciate all that NPC is doing to help DTC (District Treatment Court). It is unbelievable how you are able to capture all the important factors and information and generate a report. The report you sent looks great—just what we need to be armed with for meetings and other presentations because it is short and sweet. Yet it does manage to capture DTC and its appeal.” 
— Client representing Maryland Statewide Drug Court Evaluation

“NPC gets it done. Professional. Capable. Able to speak in non-research terms to those of us who don’t live in academia. I would definitely recommend them to colleagues.”
— Client representing Oregon Relief Nurseries

“Over this past year we have worked with NPC to adapt our instruments and the layout of our annual report to be more useful for us to be able to quickly access data that we are confident with in order to make improvements to our program.  NPC played a key role in helping us to make these adjustments … I can’t say enough good things about the quality of the work.”

— Client representing Friends of the Children

“The NPC evaluation of Healthy Start has been instrumental in keeping the program funded by the state legislature. It has solidified the reputation of the program for doing excellent work clearly leading to measurable outcomes for families. This evaluation keeps Healthy Start as one of the governor’s top priorities. The NPC evaluation also played a key role in Healthy Start becoming an accredited state system with Healthy Families America. It helps program managers and contract monitors to track their progress and change practice if needed. The work is accurate, professionally presented, reliable, and thoughtful. The customer service is outstanding. NPC is incredibly responsive to our requests.”
— Client representing Healthy Families Oregon

“NPC staff are exceptionally responsive to the needs of the client, work well with diverse groups of people, present information very well—orally and in writing—and are a joy to work with.”

— Client representing the Juvenile Accountability Block Grant (JABG) Risk Assessment Enhancement Project

“The NPC staff function as full members of our project team. Their contributions have been invaluable. They are helpful, responsive, and flexible.”

— Client representing the Oregon State Incentive Grant Enhancement for Early Childhood Prevention

“NPC understood the program they were evaluating. The work done helped provide a clear answer to the question most frequently asked: What change occurred because of participation with the CCD? … as well as providing concise ideas about improvements that could be made for future iterations of the project.”

— Client representing the Reclaiming Futures Center for Coaching and Development
