Daniel Hartnett and William Fellerhoff in Chicago are also recommended, as is Lawton Camp. Named lawyers are based in New York unless otherwise stated.

Healthcare: service providers Tier 5

Recent highlights include Kirk Ogrosky's high-profile defense of eye doctor Salomon Melgen against indictments alleging bribery and public corruption, as well as Allison Shuren's representation of multiple retina physician group practices in False Claims Act investigations concerning the treatment costs of age-related macular degeneration. DaVita, EyeCare Partners and Millennium Health are also clients of the practice.

Private equity buyouts Tier 5

Arnold & Porter operates primarily in the mid-market, though acts in larger-cap deals too for marquee clients such as American Securities and Onex. Castle Harlan has joined a client portfolio that includes DC Capital Partners, Endeavor Capital, EQT Partners, JW Childs Equity Partners and Halifax Capital Partners. In addition, the firm also advises independent sponsors, family offices, sovereign wealth funds and hedge funds on private equity-style investments. The team advised American Securities on the sale of Unifrax to Clearlake Capital Group. Emanuel Cherney is close to American Securities and Joel Greenberg has a strong connection to Onex. Stephen Koval and is also recommended, as are Kevin Lavin and Andrew Varner - unlike the rest of the team, who are based in New York, Lavin and Varner are based in Washington DC.

The team is also assisting the Republic of Peru with a series of disputes in the gas transportation sector.  Washington DC-based Whitney DebevoiseGaela Gehring Flores and Mallory Silberman are defending the Republic of Panama against a claim filed by the US subsidiaries of Bridgestone Corporation relating to its IP rights.

Latin America: International firms > Banking and finance Tier 3

Arnold & Porter's established connections to Latin America continue to bear fruit, both in the transactional and regulatory arenas. Stemming from a series of engagements for sovereign states in the 1980s, principally in connection with their debt restructurings, the firm cemented its standing with a number of ministries of finance and central banks, which in turn have led to a range of private sector bank relationships; the firm has worked with every president of Brazil’s central bank since the mid-1980s, most of whom have subsequently moved into the private sector. The firm is also a leader in bank regulatory matters, including in relation to Latin American banks’ operations in the US. Senator Christopher Dodd, a senior counsel in the firm and the man behind the Dodd-Frank legislation in the US, is playing a key role in further developing the firm’s regulatory initiatives, most notably in Brazil. On the transactional side, the firm’s merger with Kaye Scholer in 2017 has resulted in the Latin America practice having additional credibility in structured finance, securitisation and derivatives. Key jurisdictions for the practice include Brazil, Colombia, Panama, Costa Rica, Peru and increasingly Argentina. The practice advised Peruvian agro-industrial company, Camposol, on its $200m senior secured term loan facility from Banco Santander and Coöperatieve Rabobank; and in another headline deal, advised Latin American electrical power and natural gas company, Grupo Energía Bogotá, on its $749m unsecured credit facility. Whitney Debevoise has an outstanding record in Latin America, most notably with a number of central banks -such as the Central Bank of Brazil and the Central Reserve Bank of El Salvador- along with private sector lenders including Banco Itau and Banco do Brasil. Gregory Harrington is another recognised Latin America finance specialist with an excellent standing in Brazil and other key jurisdictions such as Peru. Senior counsel Neil Goodman  is an experienced counsel to sovereign states including the Republics of Colombia, Costa Rica and El Salvador. Counsels Arturo Caraballo  and Carlos Pelaez are also key members of the team. All named individuals are based in Washington DC.

Latin America: International firms > Capital markets Tier 3

Arnold & Porter continues to be at the forefront of sovereign issuances for a number of Latin American states, quasi-sovereign entities and municipalities. The firm is also noted for securitisation and structured finance transactions, including diversified payment rights transactions. Longstanding clients include the Republics of Colombia, Costa Rica, El Salvador, Honduras and Panama, Federative Republic of Brazil, Bolivarian Republic of Venezuela, Empresa de Transmisión Eléctrica, Camposol Holdings and Grupo de Energía de Bogotá. The practice group advised the Republic of Panama on its $1.2bn global bonds issuance and advised the Republic of Colombia on its  2018 global bond offering and tender offer. Outside the sovereign segment, it advised Camposol on its $500m SEC registered IPO and concurrent listing on NYSE. Whitney Debevoise has a longstanding record in Latin America and has extensive connections to Latin American sovereigns such as Brazil, Panama and El Salvador. Neil Goodman is similarly well plugged-in to the region with a history of engagements from the Republic of Colombia, the Republic of Costa Rica and the Republic of El Salvador. Gregory Harrington has an extensive record in Brazil and Peru, in particular, for clients such as Camposol; while Panamanian native Raul HerreraArturo Caraballo and counsel Carlos Pelaez  are also key members of the team.  All named individuals are based in Washington DC.
