Thomas G. Shack III, the independent overseer of more than $60 billion in state spending and assets, is stepping down as state comptroller after nearly four years, and will be replaced by a local official at the center of the recovery from last year’s deadly Merrimack Valley gas explosions.
A former prosecutor, Shack is expected to transition in the coming weeks out of an office he’s led since May 2015.
Governor Charlie Baker said Wednesday that he will appoint Andrew Maylor, currently the town manager in North Andover, as his replacement, effective Feb. 18.
Maylor was previously the town administrator in Baker’s hometown of Swampscott, including during Baker’s three-year stretch as town selectmen. When Baker first ran for governor in 2010, Maylor credited him with changing the way the town crafted its budget.
In recent months, Baker has made several appearances in the Merrimack Valley, including with Maylor and other local officials, following the gas explosions that rocked Lawrence, Andover, and North Andover, killing one and leaving thousands without heat or hot water for months.
“I am confident that Andrew will bring the level of transparency, integrity and accountability necessary for this job,” Baker said in a statement.
Shack first joined the comptroller’s office in 2012, serving as assistant general counsel, deputy comptroller, and chief operating officer before he was appointed to lead the agency. Previously, he spent eight years at the Cape and Islands District Attorney’s Office, working as a senior assistant district attorney and chief financial officer.
While not often in the public eye, the office plays a key role in helping oversee the state’s finances.
During Shack’s tenure, the office launched its CTHRU website, an open records platform that includes the state payroll, spending data, information on quasi-public agencies, and disclosures of new hires inside state government.
Shack’s office clashed in recent months with the administration over the design and implementation of computer systems. He was also at the table to help hash out an agreement after the Globe reported that neither the State Police nor Massport had publicly filed information with his office on payouts for a State Police troop dating back years.
