CMORoom Chicago

Event overview

THE MANSION HAS HELD MANY LIVES.

ON DECEMBER 15, CMOROOM ADDS ONE MORE.

100 East Ontario has never been simply an address. And on December 15, the CMORoom steps inside, bringing together a deliberately selected group of senior marketing, growth and performance leaders around modern business’s rarest luxury: the undivided attention of exceptional people.

Since 1889, the McCormick Mansion has lived many lives, private residence, casino, grand opera puppet theater and, for nearly half a century, one of Chicago’s most enduring dining landmarks.

Now reimagined by David Rockwell as The Hand & The Eye, the Mansion enters its most extraordinary era: a permanent home for magic, unexpected discovery and moments that exist only once.

Each leader will arrive with hard-won experience. Together, their perspectives will sharpen one another, challenges will be reframed and relationships will begin with the potential to influence what happens long after the evening ends.

With cameras put away, the night will belong fully to those present—unrecorded, unrepeated and impossible to recreate.

One storied mansion. Marketing’s sharpest minds. An evening that will live on through what it sets in motion.
