The Greenwalds have a large contemporary art collection, including many pieces from the Middle East. This profile in Palm Beach Illustrated he is quoted saying that: “As a diplomat, I can’t emphasize enough how much art helped me understand [a culture], particularly in the Mideast. With its potential to interpret political issues and reflect a cultural attitude, contemporary art possesses the ability to shape opinion. There’s a powerful intersection between art and geopolitics.”
