Where Real Meets Real Estate

TAG isn't just another real estate team. We're a group of real people solving real problems for real families — and we've been doing it in the San Francisco East Bay and Tri-Valley since 2006.

We're not your low-cost agents doing less for less. And we're not the luxury type showing up in Ferraris and blazers. We're the approachable experts; everyday people with extraordinary experience, here because we genuinely love this work.

We study the market. We know the process inside and out. And more than anything, we bring a human touch to a transaction that's anything but small. Buying or selling a home isn't just a deal — it's a life change. That's why we show up with honesty, strategy, and heart.

Need a late-night gut check before writing an offer? We're here. Feeling overwhelmed by the process? We've got a plan and maybe a little pep talk, too.

TAG (formally The Arsondi Group) is brokered by Keller Williams Tri-Valley Realty. Since 2006, we've helped 500+ families find their way home and closed $400M+ in sales across Castro Valley, Pleasanton, Livermore, Brentwood, Hayward, Concord, Tracy, Walnut Creek, Oakland, and beyond. But the numbers are really just proof of something simpler: we care, and we work hard for the people who trust us.

No ego. No gimmicks. Just real people who care deeply and work smart.

That's what it means to live and lead — Where Real Meets Real Estate.

We look forward to working for you.

What started with an Instagram connection is now one step closer to home. Roberto had been following Chuy’s real estate journey for a while, and when the time came to buy, they started with a clear plan and a buyer consultation. After about a month of searching, the right home finally opened its doors. Chuy moved quickly, wrote a strong offer, and negotiated $40,000 off the list price. 💛 Now they’re officially under contract on Bluebell Drive in Livermore. Congratulations to Chuy and his client on this exciting next step. TAG. Where real meets real estate. #LivermoreRealEstate #UnderContract #LivermoreHomes #BayAreaHomeBuyer #WhereRealMeetsRealEstate
