About Me

I solve problems and I help people. 


I practice business law, involving contracts, real estate and construction cases.  I also prepare estate plans such as wills and trusts, and I probate estates as well. I handle serious personal injury cases, and I also do some criminal defense work.  Over the years I’ve developed relationships with attorneys who practice in certain specialized areas, and if you were to have a problem in one of those areas, I could refer you to an attorney that I know or have worked with who would be able to help you.


I have extensive jury trial and litigation experience, and have tried both civil and criminal cases, including civil medical malpractice, wrongful death and product liability matters, and criminal felony and misdemeanors. I reopened my solo practice in Napa in 2010, and was contracted to Narayan & Hudson, Zurich Insurance, San Francisco Staff Legal, through the Mergis Group.  I practiced with Rogaski, Preovolos, Weber and Patterson, LLP. in from 2007 to 2010.  Before that, I was a sole practitioner in Napa for 14 years.  Prior to that, I practiced in big firms, and was a partner in a 145 attorney, 15 office firm.


I am admitted to the Federal District Courts in the Northern, Eastern, Central and Southern Districts of California.


In addition to having worked hundreds of automobile casualty cases, I have also handled primary case areas of Construction Defects and Construction Site Injuries, Environmental Law, Medical Malpractice, Real Estate Broker and Agents Negligence, Land Fraud, Product Liability, Design Professional Errors and Omissions, Wrongful Death, Pesticide Contamination, Nuisance and Insurance Coverage.
