We hired Campbell Rinker to do the near-impossible: help us understand our very dynamic constituent base better. The discrete groups that make up our audience are so diverse it seemed impossible to get a cohesive handle on their needs and desires. Their team was creative and resourceful in helping us figure out how to attack the problem and come away with actionable, helpful data.

I think Dirk Rinker could be the man to take on the whole firmament of lapsed and lapsing donors, and win. Dirk has an advantage over the rest of us, and it’s based quite simply on knowledge.

I have worked with Dirk on a number of projects. He is always extremely professional, and has great insights that help his clients get the most out of their research. I highly recommend him.

Team Campbell Rinker, thanks for the great research process you led us through. It showed us some things we expected, and others that showed clear direction. As a result, our Board has unanimously adopted a new name to launch the first of the year. Your research results were extremely helpful in guiding us to this conclusion and added tremendous credibility to our recommendation.

The California Society of CPAs has worked with other marketing research firms in the past, and I certainly preferred working with Campbell Rinker.
