Joseph Z. Hellerstein, Principal

Joe has a diversified practice, which covers a wide range of international law.  Joe’s practice is client driven in that his clients, based on personal relationships and attention, rely on Joe’s guidance through business ventures, corporate transactions, dispute resolution and to provide general corporate advice in connection with all Israeli business ventures.

Joe is an experienced transaction lawyer representing both companies and investors in a wide range of financing transactions involving debt and equity. Joe also represents both acquirers and targets in cross-border M&A transactions, with particular experience in representing US acquirers of Israeli companies.

Joe also represents US companies involved in international commercial disputes in both Israeli courts and arbitration proceedings.  Because Joe started his career as a New York litigator, he has the unique ability to bridge the gap between US litigation counsel and the Israeli litigation proceeding, so US counsel can closely follow the proceeding and provide strategic input.  Joe also provides legal opinions on US law in connection with Israeli litigation, regulatory and  administrative matters.


Joe graduated from Cornell University in 1992 (BA) and from Fordham University School of law in 1995 (JD).

Bar and Professional Admission
