About Cecilia Cook

Cecilia “Ceci” Cook brings over ten years of expertise in real estate, specializing in the Peninsula and South Bay regions of the San Francisco Bay Area. With a Bachelor of Science in Business Management, teaching credentials, and a DRE certification, Ceci is well-equipped to navigate the complexities of buying and selling homes.

Ceci's professional journey began at the age of twelve, when she sold groceries in her father's store. Her first adult position was in Telecom Business Sales in Auckland, New Zealand, where she served in an administrative role. A notable early volunteer experience was with a youth group in Vavau, Kingdom of Tonga, known as 'Lataki.' This group regularly visited local prisons to share meals and prayers, creating lasting memories for Ceci. She has also contributed her time to Crisis At Home Intervention in San Francisco and the East Palo Alto Senior Center. Currently, Ceci serves as a Director on the Parents' Board at Sonoma Country Day School, among other community engagements.

Ceci's diverse life experiences enhance her effectiveness as a real estate agent. She understands that real estate transactions involve not only sales but also the emotional significance of clients' homes. Living in wine country has deepened her appreciation for the parallels between real estate and agriculture, particularly as she now sells both residential properties and vineyards. Her childhood memories of her father's vanilla farming business—marked by meticulous processes from land leasing to harvesting—inform her approach to real estate. Ceci recognizes that success in both fields requires dedication, patience, and a commitment to building strong relationships. In real estate, as in farming, the journey is often long and challenging, but Ceci's persistence and expertise ensure that her clients receive the highest level of service.

When businesses need to reach working real estate agents in Sonoma County, a verified agent email list is the fastest way in. Mortgage lenders use it to introduce loan programs directly to agents who can send referrals. Title companies use it to pitch closing services. PropTech companies use it to demo software. Recruiters use it to poach top producers. Insurance providers and continuing education companies rely on it to put offers in front of a captive licensed audience that has ongoing professional obligations and purchasing needs.

This list covers every actively licensed real estate agent operating in Sonoma County, California — {{AGENT_COUNT}} agents total, with {{CELL_COUNT}} cell phone numbers included for campaigns that go beyond email. Whether you are running a cold email sequence, a ringless voicemail drop, or building a custom audience for LinkedIn matched targeting, this data gives you the reach to do it right. Buying a Sonoma County real estate agent email list from a source that actually maintains the data is what separates a campaign that converts from one that bounces into a void.

Why Buy a Sonoma County Real Estate Agent Email List From Dr Bill

Every record in this list is sourced directly from the California Department of Real Estate licensing database, cross-referenced against active license status, and verified for email deliverability. The list is refreshed with new agents added weekly, scrubbed monthly to remove bad addresses, and completely rebuilt from source data bi-annually. That process is why we back this list with a 96% deliverability guarantee — something no discount data vendor can honestly offer because they are not doing the maintenance work behind it.

Dr Bill has been in the list business since 2005 and has sold over 31,000 lists. That track record matters when you are putting budget behind an outreach campaign. Cheap alternatives recycle stale data and sell the same unverified file to everyone. This list is available at the state, county, city, and zip code level — and no other vendor segments agent data down to individual zip codes within Sonoma County the way we do. That granularity lets you target precisely instead of over-mailing.

How to Use This Sonoma County Agent List

Email outreach is the primary use case, and this list plugs directly into cold-email platforms built for high-volume prospecting. Zap Contact at zapcontact.com is purpose-built for this kind of campaign and works seamlessly with the file format we deliver. You can also use the data for direct mail, SMS, or phone outreach using the included cell numbers, and import the emails into LinkedIn for matched audience ad targeting that reinforces your cold outreach.

The list can be segmented by broker versus individual sales agent, letting you pitch broker-owners differently than rank-and-file agents. A recruiting firm targets those segments with completely different messaging. So does a CE provider versus a mortgage lender. That flexibility makes one list usable across multiple campaigns without buying new data each time.

Why Sonoma County, California Agent Data Matters

Sonoma County covers a wide geographic footprint that includes Santa Rosa, Petaluma, Rohnert Park, Windsor, Healdsburg, Sebastopol, Sonoma, and Cotati. Agents working these markets are distinct from agents in San Francisco or the East Bay, and a statewide blast treats them the same — which wastes budget and dilutes relevance. Local targeting means your message speaks to the market conditions and community that Sonoma County agents actually operate in every day.

With {{AGENT_COUNT}} actively licensed agents in the county carrying verified email addresses, and {{CELL_COUNT}} of them reachable by phone, you have meaningful scale without paying for a statewide file you do not need. Zip-code-level filtering lets a Petaluma title company ignore Santa Rosa agents entirely, or a lender target only the highest-density zip codes first. That kind of precision is only possible when the underlying data is built and maintained the right way — which is exactly what this list delivers.
