(CNN) - Houston will become the largest city in the country to be governed by an openly-gay person when Annise Parker takes over Monday as the city's mayor.
Parker was sworn in over the weekend in a private ceremony as chief executive of the nation's fourth largest city. Public events are planned for Monday.
The 53-year-old three-term city controller has never tried to shield her sexual orientation in any of her campaigns for public office. Parker has been with her partner for 19 years and has two adopted children.
Parker won nearly 54 percent of the vote in a runoff election last month, topping former city attorney Gene Lock in the battle to succeed Bill White, who was term limited. White is now aiming for a higher office: Texas governor.
Atlanta gets a new mayor Monday as well, as Kasim Reed is sworn in. Reed, who topped Mary Norwood in a runoff election last month, replaces two-term mayor Shirley Franklin.
