Michael Komasinski has been appointed CEO, Dentsu Americas, succeeding Jacki Kelley, who left to rejoin Interpublic in the newly created role of EVP/Chief Client Officer.  

Most recently Komasinski served as CEO, CXM International Markets at Dentsu. He joined Merkle in 2015 as Chief Operating Officer of Agency Services and was promoted to CEO in 2021. 

In 2023 he joined the Group Executive Management team of Dentsu following the integration of Dentsu International and Dentsu Japan Network. 

Hiroshi Igarashi, President and CEO, Dentsu Group Inc. Said, “While heading up Merkle, Michael oversaw the rapid growth of the organization and his experience in bringing together the skills, technology and data to grow will prove critical as Dentsu takes its next steps towards becoming a people-centered transformation business.”  

“Dentsu is at a pivotal and monumental stage in its history as we come together under a single global strategy with so much combined potential,” said Komasinski. “The Americas region is Dentsu’s second largest after Japan but is also ripe for growth at a time when brands need partners to deliver clear competitive and creative differentiation.”  

Prior to Merkle, Komasinski held leadership roles at Razorfish, Schawk Retail Marketing, The Nielsen Company, and A.T. Kearney.
