A top aide to Harford County Executive David Craig has resigned to take a private sector job.

The departure of Aaron Tomarchio, who has served as chief of staff to the county executive since 2005, was announced by Craig's office late Friday morning.

Tomarchio will join Erickson Living, a national developer and manager of continuing care retirement communities, as director of corporate affairs, according to the announcement.

"Aaron has been my most trusted aide during my term as county executive, and he was the first person that I asked to join my staff when I became County Executive in July 2005," Craig said in a statement.

"Upon taking office, I recognized the need for a chief of staff to manage the internal operations of the Office of the County Executive, and to ensure that the policies of my administration were being carried out," the statement continued. "Throughout his time here, Aaron has exemplified hard work, loyalty and dedication to public service. While I will miss his counsel and advice, I am very happy for him and excited for the opportunities that he has in front of him."

Craig, a Republican who is running for governor, will end his service as county executive in early December, when his term expires. He was precluded from running again for county executive because of a two consecutive term limit in the county charter.

"I am truly honored to have served the last eight-plus years as chief of staff to the county executive and thankful for the opportunity to see first-hand, all the critical elements that come together to make our county a truly special place to live," Tomarchio said in the statement. "I am proud of what has been accomplished by the county executive during his tenure, and was privileged to serve him and the people of Harford County."

Tomarchio, who previously worked for Craig when Craig served in the Maryland State Senate, will leave Harford County government at the end of February
