Mike Brunelle, the governor’s Executive Deputy Chief of Staff, will assume the role of Chief of Staff.
“Mary has been with me since the beginning, and I am tremendously grateful to her for her service and loyalty,” said Wolf in a statement. “Mary’s dedication to the people of Pennsylvania and to the governor’s office are unmatched.”
“Mike brings a diverse array of experience, and he knows state government inside and out,” he continued. “I am confident that Mike will ensure there is a seamless transition.”
Brunelle is former Executive Director of the Service Employees International Union (SEIU) Pennsylvania State Council and served as a State Representative in New Hampshire.
Isenhour come on board as Wolf’s Chief of Staff in July of 2015, when Katie McGinty left the position to begin her run for U.S. Senate. McGinty’s move was unexpected and Isenhour was seen as a stabilizing force with deep ties to the Governor.
Isenhour is a seasoned political operative who first joined Wolf’s team in early 2013 and guided the businessman and former Pa. Revenue Secretary to a landslide primary victory followed by a 10 point win over incumbent Gov. Tom Corbett.
Her previous campaign experience includes serving as Executive Director of the Pa. Democratic Party under Governor Ed Rendell, chairing Hillary Clinton’s 2008 Pennsylvania primary campaign, then running the State Committee’s coordinated operation for the general election in 2008.
