Fionnuala O'Sullivan was born in Lusaka, Zambia. After 10 years of teaching in Africa, her Irish father and English mother relocated to Naas, County Kildare Ireland where she attended primary and secondary school.

She graduated from Dublin Institute of Technology at Cathal Brugha Street, Dublin where she studied Food Science and Technology. While at College, work experience included a stint in the laboratories of the Irish State Abattoir.

She then went on to design her own line of clothing called FUFI CLOBBER NAAS which was showcased at her own runway show in Naas in the late 1980s.
Fionnuala moved to the US in the late 1980s-early 1990s and has been a south end resident of Seattle ever since, first in Mt Baker and currently in Seward Park.
She has worked in various management positions in the Food and Beverage industry throughout Seattle.

While pregnant with her third daughter, Fionnuala became a Real Estate agent and has been a broker since 1999 with GBK Realtors LLC, an independent, full service real estate company recognized as one of Seattle’s most successful brokerages. Fionnuala assists clients buying and selling real estate throughout Seattle and from Crystal Mountain to West Seattle to Shoreline and Medina. Described as professional, customer centered and conscientious, Fionnuala works hard to ensure that her clients remain largely referral based.

Community involvement is an important part of her life.
