About me

I have represented clients in claims involving wrongful death and serious injury in a broad range of civil practice, including claims resulting from defective consumer products, motor vehicles and industrial equipment, medical negligence, construction site negligence, motor vehicle accidents, and other complex litigation claims.  In addition, I have represented clients in such diverse areas of civil practice as NASD arbitration proceedings relating to the WorldCom corporate scandal.

I joined Sugarman as an associate in 2003 and became a principal of the firm in 2011.
