Michael Bierut is a graphic designer at Pentagram that I admire. Bierut spearheaded the Hillary for America design campaign, created the logo and brand image of Slack, and rebranded the logo of Mastercard. All these designs are not only creative but also successful in effectively communicating the brand persona. Check out the Hillary campaign to see how Bierut and his team used design elements to communicate a strong message: https://www.hillaryforamericadesign.com/work
