“Make Stuff People Care About.” When one of Lesly Pyle’s mentors said these five words, they changed everything for her. They became a beacon for how she approaches writing ads — and living life. Sure, Lesly’s worked at companies she’s proud to namedrop, like Goodby Silverstein & Partners, Apple, FCB, and now, TRG. But the thing she’s most proud of is “Pyle of Memories,” a book of amusing short stories she co-authored with 35 others as a fundraiser for dementia research. Because dementia is something 55 million people care about.
