Meet Mark

Managing Partner | Broker
For more than 18 years, The Agency Bainbridge Island’s Managing Partner, Mark Middleton has been a trusted expert in the local Kitsap County real estate scene, and is known as the preeminent waterfront property expert.

Setting and holding numerous all-time sale price records, Mark’'s expertise extends far beyond the region’s coastal properties, encompassing diverse neighborhoods and communities throughout the island and beyond. With a legacy of success and a heart for service, Mark is poised to create win-win solutions for his clients and cultivate lasting relationships along the way.

Recognized among RealTrends’ America's Best and Washington's Best REALTORS® for a decade running, Mark consistently ranks among the top five agents in the area. In addition to holding the title of #1 individual broker at his previous brokerage for many years, Mark has achieved nearly $500 million in sales volume. But numbers cannot fully capture the passion that fuels Mark’s dedication to his clients’ real estate goals.

More than just a transaction, Mark views each real estate journey as a privilege. Readily sharing his vast experience and local knowledge, Mark advocates fiercely for clients' best interests, ensuring exceptional service and productive negotiations.

Born in Concord, Massachusetts but raised in Bainbridge Island, Mark’s familiarity with the area and its real estate offerings is without compare.

“I’m not exaggerating when I say I have explored every beach, park and neighborhood,” says Mark. “I love helping
people sell, buy and invest in real estate by sharing my experience, knowledge and connections with them.” His local expertise extends beyond geography, encompassing a profound understanding of the communities and the people who call them home.

Mark’s passion also extends beyond the professional realm. An avid golfer at Wing Point G&CC, he cherishes exploring the area with his wife, and fellow Managing Partner at The Agency Bainbridge Island, Suzy Legier. They support a number of local charitable organizations, including Housing Resources Board (HRB), Fishline and Helpline House on Bainbridge Island.
