Sierra believes that authenticity, kindness, and treating people with respect are the foundation of both life and lasting relationships, and it’s exactly how she approaches real estate.
A natural people person, Sierra came to real estate after a successful career in sales, most recently in the automotive industry, where she sharpened her ability to guide clients through big decisions with patience and a level head. Buying or selling a home can be one of life’s most stressful moments, and Sierra’s calm, steady presence helps her clients navigate the process with confidence. For her, nothing beats the moment a client’s hard work pays off and she gets to see them genuinely happy.
Real estate has always been a dream of Sierra’s, and when it came time to make it a reality, joining The Arsondi Group at Keller Williams was a no-brainer. Drawn to KW’s reputation for world-class education and TAG’s culture of mentorship and hands-on training, she brings the fresh energy of a rising agent backed by the resources and expertise of one of the Tri-Valley’s top teams.
Sierra’s roots in the Bay Area run deep. Her family, with proud Southern origins in Mississippi and Louisiana, has called Oakland home for more than 60 years, building strong community ties across generations. The heart of the family is her grandfather Dennis Lewis’s legacy: R&D Ranch in Fremont, where he brought a piece of the South to the Bay Area and where the family still gathers to enjoy the land, the wildlife, and the values he passed down.
When she’s not with clients, you’ll find Sierra on horseback or in the kitchen. A self-proclaimed chef who loves nothing more than bringing people together over a great meal.
