About me

I am very much a person who wants to help people.  Taking on a defendant in a large case can be overwhelmingly frustrating and difficult unless you're properly represented. My personal commitment toovercoming those challenges and frustrations has helped me create a unique practice - a boutique litigation firm focusing on serious personal injury and wrongful death.  In my twenty years of practice I have developed the skill set and resources to handle the larger, more complex cases.
