Mary Catherine Masi

Born and raised in the stunning coastal town of Vero Beach, Florida, I began my career within exclusive communities like Johns Island Club and Orchid Island Golf and Beach Club.

 I moved to Charleston in 2019, where I fell in love with the region's rich history and Southern charm. I deepened my expertise in the luxury market at Kiawah Island Real Estate, managing a lifestyle program designed to provide exceptional service tailored to each client's unique needs. Additionally, I worked on the Residences at Salamander development in Middleburg, Virginia, an exclusive enclave within the Forbes triple five-star rated Salamander, Middleburg, where I further honed my skills in luxury home sales.

 Now, as a dedicated Global Real Estate Advisor with Daniel Ravenel Sotheby's International Realty, a legacy Lowcountry brokerage recognized for its elevated service, international exposure, and deep market expertise, I specialize in second and third-time homebuyers, vacation properties, investment homes, and resort residences. My expertise spans Charleston’s most coveted areas, including Kiawah Island, Seabrook Island, Isle of Palms, Downtown Charleston, and Sullivan’s Island. Whether my clients are seeking a refined coastal retreat, a high-yield investment, or a generational getaway, I provide expert guidance to help them make confident, informed decisions.
