Twenty-one years ago, Sandy Greenberg introduced the world to three words that would outlive most ad campaigns: “Milk’s Favorite Cookie.” For Oreo, it wasn’t just a tagline — it was the kind of idea that slips into culture, sets up permanent residence, and makes you wonder how the brand ever lived without it.

That ability — to find the insight everyone feels but no one has identified — has defined Sandy’s career.

She started as a copywriter in the big agency world — the kind who sweats every word, obsesses over the craft, and believes, unapologetically, that creativity is a competitive advantage. But instead of staying comfortably in her lane, she did something both logical and slightly rebellious: she decided she could run the whole thing. Not just the work, but the company.

So in 2015, she co-founded Terri & Sandy with her longtime creative partner, Terri Meyer. The agency quickly won a shelf full of industry awards, earned five feature stories in The New York Times, and assembled a roster of fiercely loyal clients, including Disney Princess, Gerber, and Freshpet, among others. Brands that stayed and grew — because their campaigns didn’t just break through, they propelled measurable, often transformative growth.
In 2025, Ad Age named Terri & Sandy Independent Agency of the Year — out of more than 200,000 independent agencies in America.

In addition to leveraging creativity to build brands, Sandy believes in its power to build a better world. She launched a national pro bono campaign with the U.S. Department of Justice to advocate for safe firearm storage; helped elevate awareness for Bridges Academy, a LA school serving students with learning differences; and launched Strands For Trans, creating safe and affirming salon spaces for the trans community — an initiative honored by Fast Company with a World Changing Ideas Award.

Sandy has also been honored as an Ad Age Leading Woman and Campaign Inspiring Woman. Her work has been featured on ABC News, The View, Live with Kelly & Ryan, Today and Entertainment Tonight As one of the most successful founders and CEOs in the advertising industry, Sandy hasn’t just built an agency; she has redefined what it means to lead one — proving that creative instinct, commercial rigor, and humanity belong at the same table.
