ZAG-S&W was established in 2001 through a unique joint venture of its founding firms, Zysman, Aharoni, Gayer & Co. (ZAG) and Sullivan & Worcester LLP (S&W). Our bilingual team of more than 200 lawyers in Israel and the U.S. understand the dynamics of two very different markets and can deftly bridge cultural differences on business practices, regulatory, securities and other legal issues. When you need counsel for intellectual property, tax, securities, litigation or anything else, our ZAG-S&W U.S. team delivers—in your language and in your time zone.


Recently, ZAG-S&W has led numerous debt and equity financing transactions of Israeli and US companies on U.S. exchanges, such as Nasdaq and the New York Stock Exchange.




ZAG-S&W has been active in China for over a decade, leading large and complex projects, including governmental projects, in Beijing, Shanghai, Shenzhen and Guangzhou.


The firm in China represents prominent Israeli and international companies, addressing all legal and commercial aspects of doing business in China and applying our perspective and understanding of Chinese business, culture and the regulatory environment. Our team in China includes Chinese and Israeli attorneys who speak Hebrew, English and Chinese, and have extensive experience providing comprehensive legal advice to Israeli and international companies and investors.




ZAG-S&W’s activity in Europe is conducted through Sullivan & Worcester’s London offices established by Sullivan & Worcester, our U.S. joint venture partner.
