Helping you make smart, well-informed decisions.

David Doyle’s career in sales and marketing began after graduating from Amherst College when he joined IBM in New York City as a computer sales professional. The skills he developed during this time laid the foundation for his ability to conduct business at “warp speed” and emphasized the importance of market knowledge, advanced preparation, and truly listening to clients' needs—key factors in achieving success.


Building on his IBM experience, David transitioned to the client management realm of the advertising industry. Over two decades, he rose to executive management positions at notable firms such as Saatchi & Saatchi and San Francisco's Goldberg Moser O'Neill. In these roles, he refined his expertise in strategic planning, marketing, negotiation, troubleshooting, and managing diverse teams to achieve common goals.

With this extensive background, David has brought his exceptional skill set to the real estate industry for over 21 years, helping countless clients achieve their real estate goals. His success is reflected in glowing client testimonials and a steady stream of referrals from satisfied buyers and sellers.
Since joining Vanguard Properties in 2015, David has embraced their client-focused approach, attention to detail, and innovative marketing strategies. These resources have enabled him to elevate his clients’ successes to new heights. His dedication has earned him Vanguard’s highest honor, the “21 Club” Award, as a top producer in Marin, as well as recognition for his achievements at Alain Pinel Realtors.

David’s client base spans Marin County and neighboring cities, with successful transactions ranging from entry-level homes to properties valued at over $6.5 million.
