Johnson

Add Estella Johnson, director of economic development for the city, to the list of retiring city officials. After 10 years with the city, Johnson’s last day on the job is May 23, she said Monday.

“I don’t have any plans right now — just to rest and relax and enjoy being retired,” Johnson said.

Before working as director of economic development, Johnson, whose LinkedIn page lists a master’s degree in public administration from American University, worked in the nonprofit world. While working for Cambridge she did everything from lead explorations on the future of Central Square to ensure the city was a supportive environment for small-, woman- and minority-owned businesses.

She was unsure Monday how her role would be filled. She joins other long-time employees in recent or announced departures: Margaret Drury, the city clerk, retired in February after serving since 1992; Donald Drisdell, city solicitor since 2003 and assistant city solicitor before that, retired in January; and most prominently, City Manager Robert W. Healy has announced his resignation for next year after more than 30 years overseeing municipal functions.
