PRWeek Coverage

MMC is artfully disruptive. We transform human truths into transcendent campaigns that dissolve barriers, ignite interest, and catalyze meaningful conversation for companies and brands. For over 40 years, we’ve been prompting action and driving change thru deliberate, purposeful provocations — in essence, redefining the craft of comms as an act of alchemy.

And while we have disruption down to a science, we’re nowhere near done experimenting.
