A little bit about me...

Born and raised in Avon-by-the-Sea, New Jersey, Mary McDevitt Castilleja grew up surrounded by real estate. Her parents were deeply involved in the industry; her father was the local broker in our hometown. From a young age she developed a genuine appreciation for homes, architecture, and the people who make them feel special. Mary’s background in interior design gives her a unique perspective when entering a home. She doesn’t see walls, floors and fixtures, but possibility. With her trained eye for balance, flow and detail- she loves assisting clients recognize the potential in every home. For Mary, real estate is about more than just buying and selling- it’s about helping her clients envision their next chapter. Whether a client is preparing their home for market or searching for their perfect place to call home- she brings creativity and genuine passion for connecting people to spaces that fit their lifestyle and vision. Growing up in a family of real estate professionals instilled in her a strong work ethic, a sense of integrity, and a deep respect for the trust that her clients place in her. Today, Mary’s proud to carry on that legacy by assisting others see not what a home is, but what it can become.
