Client reviews
"We have sold eight homes throughout California with many different realtors. Antonia has been the most diligent and attentive — her negotiation skills helped us sell substantially over asking price. We highly recommend her."

Why work with me
Everything I do is backed by real market data and a process built entirely around your goals — because the right outcome always matters more than the fast one.
Deep, hyperlocal knowledge of Newark and Fremont, with the Lake area as my home turf, backed by data-driven pricing strategy. I know what homes are worth, what buyers are paying, and how to position you to win — whether you're buying or selling.
Proven results — consistently selling over asking, generating multiple offers, and protecting buyers from overpaying. Strong negotiation isn't aggressive, it's strategic.
Professional, attentive, and with a strong team behind every transaction. I've talked clients out of houses. My process is built around your right decision — not my next commission.
About Antonia
I'm a licensed real estate agent at Golden Gate Sotheby's International Realty, with deep roots in Newark and the Lake area micro-market. I work primarily throughout Newark and Fremont, and serve buyers and sellers across the wider Bay Area.
Before real estate, I worked in construction. That background isn't a talking point — it's how I evaluate every home I show. I know what a foundation issue actually costs. I know when a renovation is cosmetic versus structural. I see what other agents miss.
I'm a mom of two, a community volunteer, and someone who takes this work seriously because I know how much is at stake for the people I represent.
My process is simple: understand what you actually need, give you honest advice, and don't stop until we get there — even if that means a 1.5-year search or closing a deal from a different time zone.

My approach is a client-first philosophy that puts your goals, timeline, and best interests above everything else. No pressure, no chasing commissions. Just honest guidance from someone who genuinely cares.
