I’m John Cavalli, a mobile notary and certified signing agent based in Castro Valley, CA. Through Notary Public Castro Valley, I serve clients in Castro Valley, Hayward, San Leandro, San Lorenzo, and nearby East Bay cities with professional, convenient notarial support.

I provide mobile and on-site notarization for individuals, families, businesses, and real estate clients who need a reliable notary to come to them. I also assist with loan signing appointments, helping documents move forward with care, organization, and attention to detail.

In addition to general notary work, I offer apostille and authentication services for clients who need documents prepared for use outside the United States. My goal is to make each appointment clear, efficient, and friendly while providing dependable service throughout the local East Bay area.
