Haley was a partner at Abrams Davis Mason Long, an Atlanta boutique law firm focused on taxation and estate administration that combined with Fox Rothschild in May 2021.

After law school, she received an Equal Justice Works fellowship to address the legal needs of low-income women with breast cancer. She founded and directed the Breast Cancer Legal Project at the Atlanta Legal Aid Society, a first-of-its-kind initiative addressing the legal challenges that can interfere with medical care for low-income women battling breast cancer. She later served as the Managing Attorney of the Society's Health Law Unit, addressing the civil legal issues that affect vulnerable individuals living with cancer, HIV/AIDS and ALS. More than two decades later, the Breast Cancer Legal Project continues to be a vital part of the Society’s work, reflecting Haley's vision for sustainable, purpose-driven legal service.
