Visit Stefan's web page : Stefan Walker

Stefan is driven by the belief that he has an obligation to each of his customers to help them make the best possible real estate decisions. He recognizes that his success is not measured by sales volume alone, but more importantly by successfully helping clients navigate one of the largest and most complex business transactions they will encounter. He stresses integrity and honest communication from the initial consultation through final closing and beyond.

With a BS degree in Business Finance from Santa Clara University and additional training in negotiation, contracts, and disclosures, he is considered by clients and colleagues alike as one of the leading real estate professionals in the Bay Area. As such, he is often consulted by the media regarding local real estate market trends. Stefan has been a Realtor since 1992 and has achieved many milestones during his career:

  • He has been a top-producing agent for years, consistently ranked in the top 1% of Silicon Valley agents
  • He is a licensed real estate broker (a designation achieved by only approximately 15% of all agents), and as such has obtained superior experience and expertise, and is held to a higher standard of care
  • He has achieved the prestigious “Diamond Certified” award from American Ratings Corp. for excellence in customer service (one of only a few South Bay Realtors to do so) with one of the highest customer satisfaction ratings ever recorded, based on direct input from past customers

Stefan’s unwavering commitment to protecting his clients’ interests is reflected in the majority of his business coming from repeat customers and recommendations from past clients.

Personal Background

Stefan is a Silicon Valley native, born at El Camino Hospital and raised in Sunnyvale when orchards outnumbered tech campuses.  He knows the Valley like only a native can. He comes from a real estate family, several generations deep of professional Realtors and real estate investors who own both residential and commercial properties in Silicon Valley. Stefan bought his first house as a 21-year-old college student and has been a full-time Realtor for more than half of his life. He lives in Sunnyvale with his wife, two teenagers, and one goofy dog in the same neighborhood he grew up in, around the corner from the house that his parents still call home. When not busy with real estate, Stefan enjoys relaxing with family and friends, hitting the gym, reading, and travel.
