About Fionnuala

Born in Zambia and raised in Ireland, Fionnuala has been a Seattle resident since the early 1990s. Since 1999, she has been a full-time, professional broker and realtor. My past experience as an owner and the Designated Broker of GBK Realtors - an independent, full-service company considered to be one of Seattle's most successful brokerages - has contributed enormously to my expertise and afforded me a wide breadth of knowledge in what is sometimes a baffling market! In early 2020, GBK partnered with COMPASS - a company that offers best-in-class-technology, unique programs like COMPASS Concierge, and top-notch marketing.
