Linda Robinson, founder of WPP’s Robinson Lerer & Montgomery, has left the firm after 25 years to head global marketing and communications at asset manager BlackRock.

RL&M partner Jim Badenhausen and executive VP Craig Brown are also joining BlackRock in communications roles.

Robinson, a former Reagan administration press hand, formed RL&M in 1986 with Walter Montgomery and Ken Lerer after she headed corporate affairs at then-Warner Cable Communications. She is a director of BlackRock, but will step down from that role in joining the firm.

Montgomery is CEO of RL&M while Lerer moved on to co-found the Huffington Post and serve as EVP at AOL Time Warner.

BlackRock has more than $3.6 trillion under management across a variety of holdings. The company merged with Barclays Global Investors in 2009.

A memo from BlackRock CEO Laurence Fink provided to O'Dwyer's said the hires come as the company “continues to enhance the management of our brand and reputation.”

Brown takes a director slot working under Robinson, while Badenhausen serves as managing director and global head of corporate communications. Badenhausen manages media relations and internal communications.
