  • Diane has become a trusted extension of our team

    “Diane is an exceptional moderator who consistently helps our projects run smoothly. She manages both reserved and talkative respondents with ease, creating a comfortable environment while still delivering rich, actionable insight.  Diane brings a wealth of experience across therapy areas and methodologies, and she picks up new approaches and frameworks quickly and effortlessly. Over the past six years, Diane has become a trusted extension of our team rather than an outside freelancer.  She is incredibly flexible, happily adapting on the fly as objectives evolve, guides shift, or client priorities change mid-stream. She is equally comfortable taking the lead with clients or working quietly in the background, stepping into whatever role the project demands.  On every project, Diane goes the extra mile—whether that means last-minute schedule changes, redesigning exercises between interviews, or squeezing in an unexpected deliverable.  She is a true pleasure to work with and is one of the first partners we call when we run short on internal capacity.“
