Mazor Matzkevich is a “superb competition lawyer who advises on various aspects of competition law and is able to bring value to her clients”.


Ms Matzkevich is a partner at M Firon & Co, heading the firm’s competition, antitrust and regulatory affairs department. She has extensive experience of advising leading global and Israeli companies in the antirust aspects of complex transactions and commercial agreements, such as foreign-to-foreign and inter-jurisdiction M&A through merger notification and approval process before the Israeli Competition Authority.

Ms Matzkevich is also an expert in antitrust litigation, including administrative and criminal cases, and in representing defendants in class actions, specialising in class actions brought against global incorporations allegedly involved in international cartels.

Before joining private practice in 2010 (as a partner at Epstein Chomsky Osnat & Co, which later merged into M Firon), Ms Matzkevich served as a staff attorney in the North-East Regional Office of the US Federal Trade Commission (FTC).

During her six-year tenure at the FTC, Ms Matzkevich was the lead or co-counsel on merger and non-merger cases involving various industries, including high-tech, retail, pharmaceuticals, agro-chemistry, energy, hospitals and food. 

Ms Matzkevich began her antitrust career in 1998 at the Israeli Competition Authority, and in 2001 became head of its criminal section. Matzkevich supervised the Authority's prosecutors in criminal cases and personally led its key criminal cases. She was also responsible for the Authority's regulatory activity in the water and environment sectors.

Ms Matzkevich is admitted to the bars of New York State (2002) and Israel (1998). She has an LLB (1997) and an LLM (2013) from the Hebrew University, Jerusalem. She is the co-author of the Israeli chapters in Merger Control (2011, 2014 and 2017), Cartels Enforcement, Appeals and Damages Action (2019) and The Private Competition Review (2019).
