Diane Sugden

Broker, Certified Negotiation Expert, ABR, LMS, Realtor

For over four decades, I've been a proud local, and since 2006, I've had the privilege of serving buyers and sellers on Bainbridge Island. I understand the nuances of our local real estate market and can guide you through the process. My approach to real estate is the same as my approach to life. I work hard, have fun along the way, and make friends through the process. I'm an out-of-the-box thinker and my cup is ALWAYS half full.

My strengths include communication, collaboration, attention to detail, proactive mindset, negotiation, contract strategy, and problem-solving. I am a natural nurturer, an advocate for my clients, and I put service before self. So, if you are in need, I am here to help. If you want to talk, I will listen.

I offer a high level of professional care through my concierge real estate services. 90% of my business is referral and repeat business from satisfied customers and clients. I have vast real estate experience and have personally worn many hats over the years. In addition to being a Realtor, I've been a homeowner, investment property owner, commercial property owner, property manager, and developer.

When I am not working, you can find me enjoying family time with my husband and 2 grandchildren,  beachcombing, tending my garden, or engaging in home improvement projects. Also, I'm a self-proclaimed foodie, wine enthusiast, and avid traveler.


I've worked with Diane on four transactions over the past seven years. She is very knowledgeable and is able to anticipate issues and challenges before they arise. She has immense integrity. I trust her to give me sound advice, tell me what is important (even if I don't want to hear it), and represent my interests. I would strongly recommend Diane to anyone looking for a realtor.

Diane Sugden brokered the sale of our home on Bainbridge. She was knowledgeable, experienced, professional, and determined. I have bought and sold several homes and Diane is the best agent I have ever met. I felt an instant connection with her. She really went above and beyond to sell our home. I would recommend her to anyone (buyer or seller). She is truly exceptional.
