About Me


I focus my practice on complex business litigation and transactional work including partnership disputes, franchise and fair dealership issues, theft of trade secret issues, copyright disputes and breach of fiduciary duty cases, among others. My practice also includes a substantial amount of contract drafting, business start-up work, and business succession and estate planning.
