Mayor Thomas Menino's elderly affairs chief is leaving the administration. Eliza Greenberg has served as elderly affairs commissioner in April 2004.

She is taking a job outside of city government, the Lit Drop has learned.

Greenberg is the latest administration official to step down in recent months. She follows Judith Kurland, Menino's former chief of staff, who left in December to start up a center focused on community democracy at UMass-Boston. Menino's budget chief, Lisa Signori, left in September for a post at the Perkins School for the Blind.

Before she was appointed to Elderly Affairs, Greenberg oversaw the city's Emergency Shelter Commission for two years.

"I have loved my time here, been honored to serve our city's homeless and elderly residents, learned an immeasurable amount from my boss and thoroughly enjoyed collaborating with many of you," she wrote in a late Wednesday afternoon letter to city councillors.
