Sarah has been the perfect brand strategist to help ideas42 evolve from talking about WHAT it does to WHY it does it.
She approaches her work with a mix of curiosity, rigor, and deep empathy. Her research goes deep and wide. She asks the right questions — and has picked out the key patterns of qualities that make our organization what it is. Her partnership and commitment are second to none, and she has masterfully helped bring along the team to help them understand both why a change in branding is needed and how her suggested evolution will work internally and with our target audience. Sarah describes herself as a mix of Mr. Spock and Diana Troy, which is apt. I’d add that she was our Yoda.
