‘Barry Nigro has the rare combination of DOJ and FTC expertise that is invaluable to clients who need to understand the agencies’ latest thinking.’

‘Fried Frank’s Antitrust practice is excellent at the big things and the small things. Not only do they have a great knowledge of the law, the markets, and how investigations work, but they are also great at guiding a company in both the pre-deal antitrust analysis and in any review of a transaction. Their relentless hard work and attention to detail is second to none. They also give you the thoughtful and insightful advice you need, not necessarily what you want to hear. ’

‘Nate Asker is excellent. He knows what he’s talking about. He’s great at talking to high level executives and CEOs and also good at explaining complicated concepts into simple easy to understand terms. He also puts in the time to really understand our business and thereby is well positioned to advise us. We also worked with Aleksandr Livshits, who was incredibly knowledgeable, thoughtful, responsive and very hardworking.’

‘The rejoining of Barry Nigro is a great move for the firm. His decades of experience generally, and recent experience as the number 2 lawyer in the Antitrust Division, makes him a knowledgeable and skilled counselor on a broad array of government enforcement matters.’
