Another big shake-up at Walter Investment: Head of Ditech Financial departs unexpectedly 

Just two months ago, when Walter Investment Management Corp. named its fourth different CEO in less than a year, some questioned whether the company was in a state of upheaval. Now, those questions seem prescient, as just two months into the tenure of Anthony Renzi, who took over for George Awad, who took over for Denmar Dixon, who took over for Mark O’Brien, Walter Investment and one of its most prominent subsidiaries are going through another executive shake-up.
