We’re the best kept secret in luxury/lifestyle strategic communications... That’s ok with us—we prefer people talk about our clients.

“SDA is a boutique luxury/lifestyle PR agency with a distinctive eye for style, and an insatiable curiosity about the world. We make lifelong friends with our clients and our partnerships thrive using both subtlety and high influence – and always humor. We create client potions mixed strategically and differently every time. We’re famous for our work in a cognoscenti world because we take a long-term perspective, have incurably youthful enthusiasm, the wisdom of age and a very long memory. Every single client, legendary and current, began with a launch… then we continue to keep interest fresh throughout the brand lifecycle. In nearly three decades, SDA has launched more than 100 evocative brands around the world.”
