Sienna was raised on Cape Cod, where real estate runs in her veins. She is a proud third-generation professional and a valued member of the Sandra Tanco Group. Founded by Sandra Tanco—a market icon with over $1 billion in career sales and 1,400 successful transactions—the team has evolved into a powerhouse three-generation family collective.
What sets Sienna apart is her unique ability to blend tradition with innovation. While she honors her family’s decades of expertise, Sienna brings a modern, forward-thinking approach to the business. Her deep knowledge of Cape Cod's timeless charm, paired with a sharp eye for emerging market trends, allows her to deliver exceptional results for buyers and sellers alike.
When Sienna isn’t helping her clients, you can find her aboard her grandfather's commercial fishing boat, reeling in Bluefin Tuna and Striped Bass. It’s this connection to her coastal roots that deepens her appreciation for the unique lifestyle Cape Cod offers—and inspires her dedication to helping others find their own piece of this special place.
Whether you're searching for a luxury seaside retreat, a year-round home, or a sound investment property, Sienna’s local insight, attention to detail, and unwavering commitment to her clients ensure a seamless and pleasant experience. With Sienna, it’s not just about finding a house—it’s about finding the perfect place to call home on Cape Cod.
