I’m Chauncey Markham, a notary public and signing agent based in Castro Valley, CA. Through Purpose Driven Investments, Inc., I serve clients throughout Alameda County and nearby Contra Costa County areas with professional, friendly notary support.

I offer convenient mobile notary service as well as retail notary assistance, helping individuals, families, and businesses handle important documents with care and attention to detail. As a loan signing agent, I am also available for real estate and lending-related signings that require a steady, organized approach.

My goal is to make each appointment straightforward and reliable, whether you need general notary work, mobile service at a convenient location, or support with loan signing documents.
