About me

Success is the hallmark of effective litigation and counseling. 

I help a broad range of clients from workers and employers, to property owners and businesses who have been wronged.   I have successfully helped those victimized by unlawful practices.   I have successfully obtained substantial awards and settlements against abusive employers, and I have successfully defended businesses and individuals against improper claims.   

I have helped employers create and implement strong policies and practices to avoid or defend against problems, and I defend businesses through negotiation, mediation or litigation, if needed.

As a civil litigator since 1993, I have helped my clients obtain substantial awards and judgments in cases ranging from physical assaults and domestic violence, to resolving business disputes, real estate and construction disputes, among others.
