Adair grew up in a double-wide trailer in Williston, South Carolina, the daughter of a cabinet maker and a public school teacher who raised her with a deep commitment to her Christian faith and family. Her parents worked tirelessly to provide opportunities for her and her twin brother, with her dad often working from before she woke until after she went to bed.

A self-described math nerd, she worked hard, graduated as valedictorian of Williston-Elko High School, and received a full scholarship to attend Furman University, where Adair met Bryan Boroughs, a classmate who would become her husband. Adair was named a Truman Scholar in 2001 and graduated summa cum laude from Furman in 2002.

After college, she taught math at Mauldin High School in Greenville County, where she learned firsthand the joy of teaching and the challenges of working within an inequitable education system. Determined to effect change for South Carolina’s children at a policy level, she attended Stanford Law School. There she was President of the Stanford Public Interest Law Foundation and Editor-in-Chief of the Stanford Law and Policy Review.

Turning down big salaries at corporate law firms, Adair began her legal career at the United States Department of Justice in Washington, DC, where she represented the American people by going after corporations and millionaires who cheated on their taxes. While there, she received multiple awards for her work and successfully led the efforts of the Assistant Attorney General’s Diversity Committee to reform hiring practices.

In 2013, Adair moved back to South Carolina and clerked for United States District Judge Richard M. Gergel in Charleston, working on a number of cases including United States v. Dylann Roof, where the defendant was convicted of killing nine African-Americans during a prayer meeting at the historic Charleston Emanuel AME church.

Then, with an eye toward supporting hard-working, low-income families like those she grew up with, Adair helped launch Charleston Legal Access, a nonprofit law firm that provides affordable legal services to those in the middle—those who don’t qualify for free legal services but cannot afford the high cost of private attorneys. Since its founding in 2016, CLA has put over $1.4 million back in the pockets of working-class families through its representation.

Adair has been an active community leader since her Furman days when she taught English as a Second Language with the Greenville Literacy Association and led diversity and inclusion workshops in the local community. She is an alumna of the Riley Institute’s Diversity Leaders Initiative, former chair of the South Carolina Bar’s Diversity Committee, former President of the Truman Scholars Association, and an alumna of the Young Leaders Program of the Council for the United States and Italy.

Adair's husband, Bryan Boroughs, is a policy attorney who has worked for the U.S. Senate on the Health, Education, Labor, and Pensions (HELP) Committee as well as numerous government and nonprofit organizations. The Boroughs live in Columbia with their daughters Annalia (7) and Rory Paige (4).
