Kaitlyn Sebastian

As one half of the Archini & Sebastian Group, alongside my business partner and longtime friend, Gianna Archini. Both born and raised on the Peninsula, our story began over a decade ago at Aragon High School, and the friendship we built then is the foundation of our partnership today. Together, we bring clients not just two agents, but a trusted team that is fully committed to their success.

My own path to real estate was shaped by my background in hospitality. Having worked in some of the Bay Area’s most acclaimed restaurants, I learned to thrive in fast-paced, competitive environments while staying patient, detail-oriented, and focused on creating meaningful experiences. I carry that same approach into real estate, ensuring that every client feels supported, informed, and cared for. I believe the journey to finding a forever home should be as enjoyable and stress-free as dining at your favorite restaurant.

I’m fluent in both English and Spanish and bring a deep understanding of the Peninsula’s neighborhoods, schools, and culture. Gianna and I combine our shared local knowledge, strong work ethic, and passion for people to help buyers and sellers alike achieve their goals. We are active members of SAMCAR, the National Association of REALTORS®, and the California Association of REALTORS®.

At the heart of it all, our mission is simple: to guide you with care, advocate for your best interests, and help you find the place you’ll be proud to call your dream home.
