[3][4] Donigan was president and CEO of Sapphire Digital starting in 2015, a website that analyzes health care plans previously named Vitals.

"[8] Prior to her tenure, Rite Aid had lost market share to competitors CVS and Walgreens, and carried significant debt.

Donigan planned to focus on fewer markets where the brand still was competitive, and expand the services provided by in-store pharmacists, a strategy supported by industry analysts.

[10] In April 2020, Donigan spoke at a press conference with President Donald Trump to speak about Rite Aid's commitment to COVID-19 testing.

[11] Due in part to the pandemic, Donigan's tenure included a move toward remote work for Rite Aid corporate employees, as well as an expansion of digital delivery systems for pharmacy customers.

[12] Donigan was credited with avoiding the bankruptcy for Rite Aid by pushing debt payments due in 2022 to 2025; however, Deutsche Bank warned the company was in danger of a "dramatic negative inflection point" in April 2022.
