About Mark Spaulding

**Biography of Mark**

**Personal Background**
Mark is a lifelong Californian, having spent his early years in Southern California before relocating to Northern California in 1972. Alongside his father, he helped build their family home in the picturesque region of Sonoma County. Married to Sharon since 1980, Mark has called various communities in Sonoma County home, including Occidental, Sebastopol, Santa Rosa, and Windsor. He takes great pride in his family, which includes four children—Veronica (32), Lauren (30), Samuel (27), and Anthony (8)—as well as three grandchildren. The family welcomed Anthony through adoption in 2011, bringing an abundance of joy into their lives. In addition to his family commitments, Mark and Sharon serve as foster parents for Sonoma County, providing care for special-needs and drug-exposed newborns, an endeavor that brings them immense fulfillment.

**Professional Experience**
Mark dedicated the first 22 years of his professional journey to Hewlett Packard, which later became Agilent Technologies. He began his career in manufacturing and, after earning his degree, advanced into management roles. His experience leading diverse teams has equipped him with valuable business acumen that translates effectively into his real estate practice. In the latter part of his corporate career, he served as a Senior Commodity Manager, overseeing regional and global suppliers, negotiating contracts, and fostering long-term partnerships.

**Educational Background**
A graduate of Analy High School in 1978, Mark pursued further education at Santa Rosa Junior College, accumulating over 70 units. While at SRJC, he began his tenure at Hewlett Packard and continued his studies, ultimately completing courses toward an Associate's degree. His educational journey extended through both Hewlett Packard and Agilent, as well as Sonoma State University, where he focused on professional development in areas such as management, team building, contract negotiation, and database management. Today, he stands as a Top Producing Realtor® and a licensed foster parent in Sonoma County.

**Personal Interests**
In his leisure time, Mark enjoys camping with friends and family, reading, and maintaining a vegetable garden. He finds relaxation in playing guitar and capturing moments through digital photography. Kayaking the waterways of Sonoma County is another favorite pastime, often shared with friends. He and his son, Samuel, bond over working on his Jeep and brewing beer. Weekend getaways to Mendocino and vacations in Maui and Lake Tahoe are cherished traditions. With family residing in Hawaii, Mark frequently visits the islands, embracing the local culture, community, and beautiful beaches.

Mark looks forward to the opportunity to connect and assist you in your real estate journey.

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.
