Allen & Overy (A&O) has formally launched in Sao Paulo, opening an office led by New York-based project finance partner Bob Kartheiser, who also co-heads the law firm’s Latin America practice group

Kartheiser will split his time between New York and Brazil while senior counsel Bruno Soares has relocated to Brazil full time. The office will start out with three full-time lawyers on the ground in Sao Paulo. Around 30 of the magic circle firm’s lawyers have a Latin America focus.
