Our Team Accolades


The Sternsmith Group is built on the belief that a strong knowledge of the community is central to providing our clients with the best experience. Our distinguished clients significantly benefit from our personal real estate portfolio that includes land and residential acquisitions and sales, development, and property management. Each member brings a unique background and set of skills - from owning a local jewelry business, to tech sales, to hospitality, to retail marketing, and volunteering to increase opportunities for private school education, - we’ve created a dynamic, hardworking group that can tackle a variety of challenges. Add to the mix nearly two decades of experience and it’s easy to see why we’re consistently #1 in San Mateo and are #2 in San Mateo County.

What Clients Say


Premier agents! We began the search for our home during the pandemic when nothing felt certain in the housing market. Casey and Tess gave us the hope we needed with their encouraging attitudes and sincerest advice. This duo is proactive, quick, and well versed in the housing market even in the most unpredictable times. We never felt like it was just another sale for them and rather truly felt their investment in finding a home for our family.


Casey and her team are true professionals. They listened to what my wife and I were looking for, showed us options, and then executed fast. They were always available to discuss details and strategy and easy to talk to. Most of all their experience, market knowledge and strong negotiating really helped to make sure we got our new home at the right price without overpaying. We could not be happier with our experience and can't believe it was so easy.


Tess is a true gem! She represented us as both buyer agent and seller agent (we bought in 2017 and sold in 2022). She is an amazing person and truly on your side! She is thorough and knowledgeable and client-centric. Tess really made the selling process so seamless and took charge. She takes care of her clients. We also recommended her to friends who had her represent them in the buying and selling process and they share the same view. Tess gets the job done and she does this effectively and efficiently! We are so lucky to have had Tess represent us on our purchase and sale of our San Carlos home.


Our tagline has always been "Your realtor matters; Experience the difference." To us that means being client centric, operating with complete integrity, and working to astonish our buyers and sellers with each transaction.  For our buyers, we focus on listening intently to what their dream home is and helping position them to purchase it.  For sellers, it is using our expertise in property preparation, luxury marketing and exceptional negotiation to secure the highest possible price with best terms for our client.  Our clients span the San Francisco Peninsula, including Hillsborough, Burlingame, San Mateo, San Carlos, Belmont, Redwood City, Redwood Shores, Millbrae, Pacifica and San Bruno. We can't wait to help you.
