After a little more than three years away from her former firm, Maria Chedid is returning to a different Arnold & Porter Kaye Scholer.

Earlier this year, the firm started marketing itself again as Arnold & Porter, almost a year after it absorbed Kaye Scholer in a move that boosted its head count and gross revenue.

Chedid re-joins Arnold & Porter after leaving Baker McKenzie, having served as the global legal giant's California arbitration practice chair after coming aboard in early 2015. Baker McKenzie hired Chedid from Arnold & Porter that year after she spent nearly a half-decade at Arnold & Porter, a firm she first joined in 2010 to establish and lead its West Coast arbitration practice.

Once again ensconced at Arnold & Porter, Chedid will once again be a partner in San Francisco, focusing on international arbitration matters. She was not immediately available Thursday to discuss her decision to return to Arnold & Porter, which she noted on her Chambers and Partners profile and biography page on professional networking website LinkedIn.

Maria Chedid.

Chedid has more than two decades of experience in international dispute resolution. She was appointed president of the Northern California International Arbitration Club in 2014. Before coming to Arnold & Porter for the first time in 2010, she spent roughly 15 years at Morrison & Foerster, where she began her private practice career in 1995.

Arnold & Porter first planted its flag in San Francisco in 2005. Since then, the firm has significantly expanded its operations in the Bay Area, a move helped in part by its merger with Howard Rice Nemerovski Canady Falk & Rabkin on Jan. 1, 2012. That combination doubled Arnold & Porter's California presence, which now included hundreds of lawyers in San Francisco, Palo Alto and Los Angeles.

Following the union between Arnold & Porter and Kaye Scholer on Jan. 1, 2017, the combined firm now has nearly 1,000 lawyers—300 of them partners—with gross revenue approaching the $1 billion mark. Arnold & Porter now has nine domestic offices and four abroad.

According to its website, Arnold & Porter's San Francisco office is among the 30 largest law firm offices in the city. Its localized expertise includes complex commercial litigation, corporate and securities transactions, intellectual property rights, environmental compliance and antitrust and international litigation.

Chedid, who is fluent in Arabic, had advised clients in disputes in Africa, Asia, Europe, Latin America and the Middle East. Her dispute resolution portfolio includes areas such as licensing, intellectual property, energy, political risk insurance, construction, breach of government contracts and joint ventures.
