Simi Valley, California

I live and work in Simi Valley and have been practicing law for more than fifteen years.

I love practicing law in Simi Valley and providing my community with personal, attentive, and experienced legal services, with integrity and effective advocacy.

In 2006 I started my own practice in Simi Valley, and my practice now serves all of Ventura County and parts of Los Angeles County. My areas of practice include in large part, meeting my clients’
 estate planning needs and probate concerns.  In this area of my practice, I have prepared hundreds of estate plans, which include wills, trusts, powers of attorney, health care directives, etc.  and represented clients in numerous probate matters in Ventura County and the surrounding areas.  I also assist my clients in range of civil matters including real property and business disputes.

Prior to law school, I worked in the public service sector from 1987 to 1994, first in a U.S. Congressional office, and thereafter as community outreach coordinator for the City of Los Angeles, Environmental Affairs Department.

I graduated from Southwestern University, magna cum laude, in 1997.

In 1997, I joined the firm of Lynberg & Watkins in downtown Los Angeles. There, I worked on complex multi million dollar environmental insurance litigation cases.

I wanted to work in my community of Ventura County and also serve the public interest and so in 1998, I joined the Ventura County District Attorney's office as a Deputy District Attorney, prosecuting a range of cases in which I gained valuable and substantial courtroom experience, including prosecuting a multitude of jury trials. As a Deputy District Attorney, I was called to prepare witness testimony and other evidence through which I sharpened my communication and advocacy abilities that have continued to serve me well even as I transitioned to civil practice in late 1999. From that time I have practiced in Simi Valley continually.

In late 1999, I joined the Law Offices of William J. Waters in Simi Valley. There, I worked independently on a range of civil cases including business litigation, real property, neighbor disputes, family law, bankruptcy, medical malpractice, and estate planning. I also conducted all of the firm's trials and also all cases that went to the appellate court
