Geisinger Advanced Aesthetics launched in July 2026 with a fully integrated brand campaign spanning social, streaming, digital, and print. The work made its print debut in the September issue of Vogue, with additional placements in Vanity Fair, People, Real Simple, and Better Homes & Gardens. At the heart of the campaign was Look Closer, a creative platform that revealed confidence, character, and individuality one feature at a time.
For the Ones Who Cared for You has just launched as an integrated campaign across streaming, digital, and social, reaching adult children throughout New York City in need of more care for the ones they love. Using real vintage family photographs, the campaign struck a deeply human and relatable chord, replacing traditional healthcare messaging with something far more visceral and relatable.
