Raised in a private, middle-class setting, she was an avid tennis player in youth. She studied at the Rochester Institute of Technology in New York, where she developed an interest in communications and event coordination—skills that would shape her professional path and later spark a romance.
Stoll began at the PGA of America in 2008 as an office manager, handling logistics such as golfer check-in and transportation at events. It was during this role that she met McIlroy by chance, and the two quickly formed a connection.
Her time with the PGA gave her a unique perspective on golf operations, tournaments, and the pressures athletes face, helping her navigate life with one of the game’s biggest stars.
By the time their relationship became public around 2015, Stoll had established herself as a respected professional who valued privacy. The couple has a daughter, Poppy, and has largely kept their family life away from the public eye.
In recent years, public attention has included speculation surrounding their marriage following a brief divorce filing in 2024. Stoll has maintained a private approach as they address ongoing questions about their family life.
