About me

Dedicated Attorney, Former Prosecutor

I have a diverse background in various areas of law that give me a broad, thorough legal base to provide quality services to my clients.  I am aggressive but polite, and firm but compassionate.


Criminally, I prosecuted misdemeanors for the City of San Diego with multiple trials and a winning record.  I never lost a DUI jury trial verdict for the City.  My responsibilities include reviewing thousands of cases (DUI and misdemeanor) to determine if the City should prosecute or not.  Now, you can put this former prosecutor experience to work for you.


First, I can analyze a case as a prosecutor, and clearly identify how they will view the facts.  This means I can also identify what they are likely to overlook, or any weaknesses that can be exploited.  Second, I know the prosecution procedures from the inside.  From a strategic perspective, this provides me a chance to act before they do, or adjust the litigation timeline to my client's benefit.  Third, I know what will best produce judicious results for my clients in negotiations.  I know how to present factors or evidence to them in the most palatable, favorable light as they see it.  Lastly, there is professional respect from having done their job: we are opposing counsel and viciously fight for our client's best interests, but it can be done with civility and decorum.


My civil work for the City of San Diego includes reprsenting the Transportation and Engineering Design Division (TEDD) in the Engineering and Capital Projects Department.  TEDD handled transportation construction contracts and amendments in the City.  I handled dozens of contracts and amendments from initial review to City Council ratificaiton, including drafting City Council resolutions and ordinances.  Although I kept a low profile, I worked on some of the highest profile and controversial projects in recent City history.  Now, I offer my clients inside knowledge of City contracting procedures to either negotiate a resolution, or recommend an efficient course of action.

For the County of San Diego, I reviewed all projects requiring grading over 200 square yards for environmental law compliance- from driveways or tennis courts to multi-million dollar developments.  My knowledge of municipal development or permit approval is available to clients to help facilitate project approval, or negotiate mitigation requirements.
