Former first lady Michelle Obama will speak at the 14th annual Pennsylvania Conference for Women in Philadelphia on Thursday, Oct. 3.

Obama served as first lady of the United States from 2009-17. During that time, she launched initiatives including Let's Move!, to address the challenge of childhood obesity; Joining Forces, to support veterans, service members, and their families; Reach Higher, to inspire young people to seek higher education; and Let Girls Learn, to help adolescent girls around the world go to school.

Before becoming first lady, Obama attended Princeton University and Harvard Law School. She worked as an attorney at the Chicago law firm, Sidley & Austin, where she met her future husband, former President Obama. She later worked in the Chicago mayor's office, the University of Chicago, and the University of Chicago Medical Center.

"We are honored and thrilled to have Michelle Obama, one of the most respected women in the world, join us at this year's conference," Leslie Stiles, board president of the Pennsylvania Conference for Women, which will host its event at the Philadelphia Convention Center, said in a statement.

"With her career-long devotion to improving the lives of children, increasing nutrition awareness, and advocating for equal access to education, Michelle Obama's impact clearly extends beyond her White House years," she added.
