I’m Xochi Martinez, owner of Two-Tone Notary & TC, LLC, based in Castro Valley, CA. Established in 2022, I provide in-house and mobile notary services, along with real estate transaction coordination support, throughout Alameda, Contra Costa, and Santa Clara counties.

I specialize in real property, estate planning, and loan signings, and I bring a science and technical background that helps me work comfortably with maps, property descriptions, inspections, technical reports, regulatory compliance, and surveys. I am a California Notary Public, Commission #2409616, with a CA notary license expiring July 2, 2026, and I am also a Licensed Realtor® with CA DRE #02145611.
