About The Mashore Group
When you do what you love, people love what you do.
Most agents put your home on the MLS and hope. We don't do that. We create attention. Most agents rely on exposure.
The Mashore Group is a Contra Costa County real estate team built on a real digital marketing system. Jaynlin Slone runs the listing and buyer work on the ground every day. Krista Mashore is the national authority who built the system Jaynlin runs locally. Together they serve all of Contra Costa County: Brentwood, Oakley, Antioch, Discovery Bay, Walnut Creek, Concord, Martinez, Danville, San Ramon, and Orinda.
Marketing is the engine that creates demand. Demand creates leverage. Leverage is how you get top dollar and the best terms. That's the principle behind everything we do for every seller and buyer in this county.
Jaynlin Slone — Lead Listing Specialist & Marketing Specialist | DRE #02195224
Jaynlin leads every listing and buyer transaction at The Mashore Group. She has spent more than a decade in East Bay real estate doing the on-the-ground work: preparing homes, running digital campaigns, communicating clearly at every step, and getting deals closed.
Instead of putting your home on MLS and hoping the right buyer finds it, Jaynlin runs full digital campaigns across social media, video, and targeted ads. Clients mention her consistently in reviews for one reason: she stays in touch.
Jaynlin co-authored "The Savvy Seller" and "The Home Buyer's Blueprint" alongside Krista, and created The Savvy Home Seller Course and The Home Buyers Blueprint Course, which every Mashore Group client gets access to. That work is backed by The Mashore Group's collective track record: 2,350+ homes sold and 19 consecutive years as a top 1% team nationally.
