Yvonne O’Kane

Lifestyle Realtor

Yvonne O’Kane believes that Real Estate is much more than the transaction, because it’s the connection to the people who live inside each home that matters most. Her combined passions for design and sales have led her to a career as a Realtor®, where her mission is to help clients achieve their lifestyle whether buying, selling or renting their home.

Westport Resident
A Westport resident for the last 14 years and the parent of three children who attend or have graduated from Westport’s public schools, she has a local’s working knowledge of the community. Her extensive knowledge of Westport and Fairfield County means she can help highlight all that the area has to offer: the Arts, Beaches/Boating, Performing Arts, Shopping, Fine Dining and most of all a strong, vibrant community to live in.

Yvonne is a double graduate of the Rhode Island School of Design, with both a Bachelor of Fine Arts and a Bachelor of Architecture. These degrees, along with her genuine love of homes and interiors, make her an invaluable resource when buying and selling a house. Prior to living in Connecticut, she worked in NYC. She designed multiple suites for Sony’s executives, worked on the redesign of the LA Library and redesigned all metro area branches for NatWest Bank. Each project allowed her skills and creativity to develop and refine, and she continues to use her eye for design and structure to give valuable insights to her Real Estate clients.

Community Devotee & Philanthropist
While on an architectural hiatus, Yvonne has had the honor and privilege of raising her three beautiful children, which allowed her to be deeply involved in her community. She has held many volunteer positions on the Executive Boards of the Westport Schools and the National Charity League, as well as Manager positions with sports associations, including Westport Soccer, Staples Cross Country, Indoor and Outdoor Track teams and Staples Soccer. Thru each of these organizations she has been directly responsible for tremendous fundraising results and philanthropy work in the Westport and surrounding communities. She is currently beginning a long term project with Circle of Care, redesigning rooms for children with cancer.

Yvonne is passionate and detail orientated in all she does and will always represent your best interests. Mar Jennings Lifestyle Homes is delighted to have her on their team of Lifestyle Realtors.
