Tina began her real estate career in San Francisco in 1976 assisting the owner and multiple agents of one of the City’s most successful high-volume brokerages. She developed a deep understanding of every aspect of real estate — knowledge that helped her become the veteran Bay Area industry leader she is today.

Highly self-motivated and committed to confidentiality and positive outcomes for her clients, she joined Sotheby’s International Realty in 2004 and consistently ranks among the company’s top producers, regularly securing top-tier sales volumes in both the town of Sonoma and across Wine Country. Clients and colleagues alike admire her in-depth experience, stalwart professionalism, impeccable reputation, strong work ethic, artful negotiating skills, insightful marketing capabilities, warm demeanor, and seasoned navigation of complicated transactions. Tina assists buyers and sellers of all types of properties in the Bay Area and Northern California’s wine country, from rural and equestrian estates to vineyards, historic homes, and new developments.

Her relationship with Sotheby’s International Realty allows her to offer clients access to strategic regional, national, and international markets; high-net-worth individuals and an extensive global network of associates and clients. Alongside her son and daughter — both adept sales agents in their own right — and several administrative and marketing team members — she helms the Shone Group, providing clients multiple decades of experience and expertise buying and selling in Sonoma, Glen Ellen, Kenwood, Napa, and Marin County. During her free time, Tina enjoys spending time with her family and delving into history, the arts, and current events.

Tina Shone has a deep understanding of the industry’s intricate processes resulting in artful negotiating skills, insightful marketing and a unique ability to close complicated transactions.


How does one gauge a quality like appreciation? Through experience we learn which things bring us joy and peace and which things make our lives harder and darker. The attributes and qualities that you bring to the maddening world of real estate transactions is a breath of fresh air creating an environment of peace and clarity for your clients.

I said at the onset after our first meeting that you have a great family energy that shines. That energy and light guided this entire transaction. The one concern I had before hiring your group was that we would not get the attention and care of a more substantial property. My concerns were not only alleviated but completely erased as the opposite was true. The attention to detail and concern from every member of your group was impeccable. Each of you brought valuable tools to make this transaction seamless and stress-free.

Tina, the respect, grace and wisdom that you exhibit begins with your beautiful relationship to your children and it shines through every facet of the transaction, creating an atmosphere of tranquility through which we worked.

Amanda, your omnipresent being, warmth and resourcefulness never left a question unanswered or task undone.

Evan, your down to earth honesty and clarity provided us with a broader view from which to strategize and gauge our buyers.

Trust is paramount and we greatly appreciate the trust and professionalism that the three of you have given to us.
