Barbara Alonso and Albert del Castillo, two major international dealmakers in Miami, have traded places.

Alonso, who specializes in international and domestic corporate matters, is moving this week to Squire Sanders after two years as a shareholder in Greenberg Traurig’s Miami office. She previously worked at Hunton & Williams and Shutts & Bowen and was in-house counsel at Chase Manhattan Bank in New York.

Del Castillo moved to Greenberg from Squire Sanders early this month.

Alonso said she was intrigued by Squire’s wealth of international offices, including one in Lebanon where her husband’s family lives.

"I started interviewing with Squire a while ago," she said. "I found it appealing because it’s international. I also got the impression it’s a very collegial environment, which was very appealing."

A Greenberg Traurig spokeswoman said in a statement, "We wish her well in this new phase of her career."

Alonso is one of Miami’s busiest dealmakers, helping close an $800 million sale of high-yield debt for SBA Communications Corp. in 2012.

She helped represent a European financial group and Mexico’s Banamex on a $26 million loan to a Mexican transportation company in 2011 and was on the legal team representing Banco de Sabadell in its $160 million purchase of Mellon United National Bank in 2010.

Alonso has represented financial institutions and other capital sources in a variety of domestic and cross-border lending transactions, including matters involving corporate and sovereign borrowers in the Caribbean, Latin America, Europe and Africa.

Most recently, she has acted for issuers and underwriters in transactions in Argentina, Brazil, Colombia, Costa Rica, Mexico, Peru and Venezuela.

Cleveland-based Squire Sanders has 1,300 lawyers in 39 offices and 19 countries around the world.

Del Castillo, Florida regional coordinator and a 19-year attorney at Squire Sanders, joined Greenberg as a shareholder in the public finance section. The move marked a return for del Castillo, who worked at Greenberg from 1985 to 1994.
