About me

I am a Partner at Di Maria & Cone, a Palo Alto law firm where we practice family law exclusively. I've been practicing law since 1978 and can provide my clients with extensive experience and knowledge. Our firm handles the broad spectrum of family law issues, such as child custody, child support, spousal support, property division and domestic violence restraining orders. At Di Maria & Cone, we pride ourselves in taking the time to get to know our clients because it will allow us to carefully tailor our representation to the client's goals and best interests. Also, we know that each client has a unique situation and we never lose sight of how the legal advocacy we provide affects real children and parents. We represent clients in most of the Bay Area counties, but primarily in Santa Clara and San Mateo counties. Please contact our office for a free consultation.
