We’ve received confirmation that Mullen chief digital officer Mauro Cavalletti has turned in his resignation after less than a year in order to deal with “serious family health issues” back in his native Brazil. The Mullen camp tells us that “everyone here was sad to hear the news. He’s a great guy.”

If you recall, Cavalletti and Perry Fair joined Mullen as co-CDOs last April, with the former arriving from R/GA San Francisco (where he was ECD  for three years) and the latter from an ECD gig at Grey New York. Fair of course left Mullen at the end of last year for the CCO gig at JWT Atlanta/Houston/Dallas. As of now, it appears that Mullen is not planning to immediately replace Cavalletti.

Update: Here’s a quick note from Cavalletti himself: “Leaving Mullen in this very special time for the agency makes me feel sad. However, it’s time for me to move back to Brazil as I have important personal matters to take care of there.” Cavalletti clarifies that his family is actually in “good health” (good to know) but is “asking us to be by their side.” Best wishes, my friend.
