Meet Our Team

Led by mother and daughter Lydia and Magda Sarkissian, the Sarkissian Bullock Team brings two generations of expertise to Marin’s luxury market. With nearly $3 billion in closed transactions, the team represents one of the largest inventories of luxury homes in Marin, including Belvedere, Tiburon, Mill Valley, Ross, Kentfield and surrounding communities. They are known for representing the finest homes, properties that soon become the setting for a lifetime of new memories for their owners.

Lydia and Magda are both recognized among the Top 100 agents at Sotheby’s International Realty globally. Lydia is one of Marin’s most trusted advisors, with decades of experience representing buyers and sellers in the luxury market. Her long-standing relationships with homeowners, families and fellow agents give clients access to opportunities before they reach the market, and her calm, seasoned approach to negotiation has guided many of the area’s most significant sales. Magda, a Marin native with 12 years in real estate, leads the team’s pricing strategy, contract negotiation and marketing. She is known for guiding clients through complex transactions with clarity and care, and her sharp eye for design helps buyers recognize a home’s true potential and sellers present their property at its best.

The team’s foundation was built alongside Bill Bullock, whose leadership at Golden Gate Sotheby’s International Realty and decades of transaction experience continue to shape its standards of excellence. Together, they have been the top team at Golden Gate Sotheby’s International Realty for many consecutive years.

The Sarkissian Bullock Team has set multiple records in Marin County. In 2024, they represented the seller in the $42.1 million conservation sale of Easton Point on the Tiburon Peninsula, also known as the Martha Property, the highest land sale in Marin County history. In 2026, they represented both the buyer and seller of 101 Belvedere Avenue, the highest residential sale in Belvedere since 2015.

They also hold the record for the most homes sold over $20 million in 2021, and in 2015 they doubled the previous record for Marin County homes sold over $10 million in a single year. These achievements have attracted a global network of exclusive off-market properties.

Clients work with Lydia and Magda on the decisions that matter most, from identifying the right home to preparing a property for sale and negotiating the strongest possible terms. Their personalized guidance and deep knowledge of the luxury market, combined with sophisticated global marketing, help make every transaction seamless. The team believes every client deserves luxury service, regardless of price point, and brings the same attention to preparation and follow-through to each one.

The team also has strong relationships with mortgage lenders and can help both sellers and buyers access financing with minimal disruption to their lives. Having built and renovated several properties in the community, they bring in-depth knowledge of home improvements, renovations and resale considerations to help clients .

For many years, the team has represented prominent executives and public figures in the purchase and sale of luxury real estate in Marin County, San Francisco and Wine Country, always with the highest level of discretion. Beyond real estate, they are deeply engaged in the community and passionate about environmental conservation through their involvement with WildCare.

Kim Walker, Operations Manager, and Grace Janho, Transaction Coordinator, support the team’s operations and ensure every transaction runs smoothly from start to close.
