Development Guild has been our partner over the length of our seven-year Campaign, beginning with Campaign planning. They have provided both intensely focused counsel and general strategic input. We continue to choose Development Guild because their staff offer broad knowledgeable perspectives, they understand our unique position and ambitious goals, and we trust their leadership to bring the best current Advancement thinking to the table.

We always trust Development Guild’s ability to deliver results; that’s why we engaged them to partner with us in recruiting a talented new Executive Director. Their collaborative and responsive approach and the terrific end result confirmed we made the right decision.
