Fionnuala O'Sullivan

I was trying to figure out where I could only grade four stars, because let’s face it, no one’s perfect. But with Fionnuala, I just couldn’t; it wouldn’t be honest. Five star service across the board, both with the sale of our house and the purchase of a new one. She was responsive, available and professional. Perfect!

Today’s Real Estate market is fast moving and complex!

Choose to work with a professional Realtor with a proven track record.

BACKGROUND Born in Zambia, and raised in Ireland, I have been a Seattle resident since the early 1990s. Since 1999, I have 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 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.

BOUTIQUE SERVICE My number one goal is to help my clients successfully navigate the process of buying or selling a home. By choosing to work with fewer clients, I can offer a personalized service and my undivided attention, which allows my client base to remain largely referral based.

TRUST I strongly believe that any good relationship is built on trust. Buying or selling a home can be an extremely personal and sensitive process, and is best achieved within a collaborative, understanding environment.

GIVING BACK Community involvement is important to me-I have served on many boards and as a volunteer. I donate a portion of my commission to a local non-profit.

My clients – and their families – typically use my services for every real estate transaction that they consider, or actually engage in.

I have been through many housing cycles and look forward to discussing your Real Estate needs with you.
