Leslie feels fortunate to be working with best-in-class teams across Deloitte Digital and couldn’t be happier to have such an extensive range of capabilities—business strategy, technology, data, and design—igniting their creative thinking across all aspects of clients’ business.

Prior to joining Deloitte Digital, Leslie’s career began as a copywriter before becoming US chief creative officer, first for Y&R, and then for Ogilvy, where she was responsible for setting the national creative vision for both agencies.

She’s produced award-winning and business-transforming work for companies of all kinds. From creating the first national park digital preservation platform for Nature Valley to inventing the Staples easy button, Leslie’s work has been recognized by every major global awards show for both creativity and effectiveness.

Leslie has been named one of the Top 10 CCOs in the US by Adweek, and Business Insider included her as one of the Most Creative Women in Advertising. When she was named Advertising Working Mother of the Year by She Runs It, her then-eight-year-old son wondered how she was able to receive such an honor since no one ever asked anyone in her family what they thought of her.

She has served on international award show juries that select the best creative industry work, including the prestigious Grand Effie jury in 2018 and the Cannes Lions Titanium jury in 2019. She is also a board member for The One Club for Creativity and for the Clemson University Erwin Center.

These days, Leslie can be seen walking her dog endlessly around her neighborhood while on conference calls or listening to murder podcasts. She is Mom to a 9th-grade daughter who should have her own cooking show, and a 7th-grade son whose hair she helps dye whatever color he wants. Her husband is an incredibly patient New Zealander. Her dog is tired.
