When Macias joined Pomona one of her tasks was to modernize the operations of the City Clerk's Office.
"It was very challenging at the beginning because of the state the department was in," Macias said.
The department at the time relied heavily on paper documents, and Macias worked to make a shift to electronic record-keeping.
That took place gradually but not as far as Macias would have liked due to budget limitations, she said.
Macias' work was not limited to record-keeping. During her tenure she implemented a number of community outreach programs many involving youth.
She started a program in collaboration with the Pomona Unified School District in which every quarter the City Clerk's Office mailed birthday cards to youth turning 18. The cards congratulate them and encourage them to register to vote.
"We sent over 1,000 cards before the November election," she said.
Macias also worked to recruit and train young people to serve as poll workers and carry out voter registration drives.
Through the Youth in Government Day program, which was organized for two years, teens had an opportunity to interact with city administrators and shadow them.
Youth were able "to see and experience first hand how directors work and how the city works. It was an eye-opening experience for kids," Macias said.
The Pomona Enrichment Program provides Pomona Unified School District students a means to gain a better understanding of their city and encourages them to become involved and make a difference.
The program includes visits to City Hall, opportunities to speak with department heads, visits to the city's historic sites and art institutions in the city's Arts Colony.
All together the programs "are about trying to get them involved in the democratic system," Macias said.
Such experiences can influence a young person's decision about career choices.
"You can make a difference," she said. "Some little thing that we do can be a big deal to a child."
Macias began working in local government in 1986. She worked for Placentia and worked in the areas of community development and community services before moving to the City Clerk's Office in 1995.
By 2004 Macias was deputy city clerk in that city. That same year she became Pomona's City Clerk. At the time she was also serving as president of the City Clerks Association of California.
Macias will retire and focus on her family. After a break she plans to pursue some consulting work.
"I can't see myself just sitting around," she said.
Macias last day at work was Thursday.
