Jess is a Hill Holliday boomerang where she recently returned as Head of Strategy. During her first stint at Hill Holliday, she spent over seven years working across many of the agency’s most notable accounts while leading a significant role in new business. She then left the agency to bring her talent and experience to management consulting. She joined Slalom Consulting to better define the intersection of brand strategy and business strategy. While at Slalom, Jess worked as a Principal in the Customer Strategy practice, building marketing strategy capabilities while also applying her brand strategy and customer journey mapping experience to traditional business management engagements.

But her love for the advertising industry was too strong to stay away. She then went on to join DiMassimo Goldstein, where she most recently served as Head of Strategy. During her time at DiMassimo Goldstein, her role was to lead development of strategic and research capabilities, including customer journey development, brand positioning, quantitative research and analysis, a variety of qualitative research methods, insight development, and culture trends development. Jess has returned to Hill Holliday to not just lead the Strategy team, but develop strategic consulting capabilities, all while lending her talents to advance agency capabilities and growth.
