Sonia Byrnes offers vast real estate experience with a strong sales record in both Fairfield County and New York City. Sonia joined the Darien Board of Realtors in 2013 after moving to Darien from Manhattan in 2012. A former agent at The Corcoran Group in New York City, she entered the Connecticut real estate market with 7 years of prior experience. She spent two years as an agent in Darien and quickly built a thriving business by becoming highly knowledgeable of the marketplace as well as the nuts and bolts of a purchase and sale transaction. In an effort to expand her business outside of Darien, she joined a team at the Higgins Group in Fairfield. She spent four years building a solid business in Fairfield, Westport and Norwalk, before deciding to make the move down to a Darien based office. She recently joined William Raveis, and is very excited to continue to build her career there. Sonia is a dedicated, detail-oriented professional who works hard to fulfill her clients' needs. She is both highly adaptable and extremely accessible, which are vital assets in working with any agent to ensure the finest service. Sonia believes that it's equally important to understand each client's unique needs as well as the marketplace in which you work. Sonia know that every buyer and seller are different, and have his or her own requirements, preferences, time schedule and financial options, so she takes great care to adhere exactly to what each individual needs. While being flexible and accommodating in her approach, Sonia is also creative in her thinking, and not afraid to advise clients otherwise if she feels another option might work better on their behalf. Originally from just outside of Philadelphia, Sonia earned a Bachelor of Arts degree in Sociology and Art History from Vanderbilt University in Nashville, TN. Sonia worked in marketing in the fashion industry for both Macy's and Perry Ellis for several years before discovering the tremendous appeal of real estate. She and her family, including two young daughters, moved to Darien in 2012, where they quickly immersed themselves into the community and thoroughly enjoy the town and all it has to offer.
