‘We have been with our main contact for years. He follows up on everything anyone does for us. ’

‘Available 24/7. Have helped from personal issues, kid issues to all business issues. ’

‘I think the key to Nixon’s success is the way the attorneys collaborate. No matter what the situation there is someone who has seen something similar before. The ability to draw from so many experiences – sets Nixon’s team apart.’

‘I feel like the attorneys that I work with make you feel like your family.’

Phil Taub and Andrew Share are great lawyers and even better people. ’

‘To prepare myself for the sale of my business I recognized that the first step was to understand the process and have a strong team assembled. After interviewing several firms I selected Greg O’Shaughnessy of Nixon Peabody. He had the knowledge experience and personality I was looking for and I was impressed with his support staff. The major factors for my decision was the process he proposed and his knowledge of the due diligence process. Greg and his team was there for every step I took and participated in every discussion.’

‘Atty O’Shaughnessy was always focused on the best way to get me the best deal possible and advised that the best deal is not always the highest sell price. Also they provided me at the beginning an estimate of the legal costs that would be involved and updated me if there was any change so there would be no surprises. The billing was always concise and billed timely with no surprises. Atty O’Shaughnessy and his Associates were exceptional and I do not hesitate to recommend their legal services.’

‘They understand the needs of the business and balance legal risk assessment with strategic goals. Very practical and actionable advice is a hallmark of the firm.’

‘Andrew Share is our go-to partner. He understands the needs of in-house counsel and the pressures we face. He does an incredible job of assessing our legal requirements while also taking business needs into account. He makes my job manageable in a very small in-house legal department with limited resources. Having the assistance of Andrew is like having another four lawyers on my staff. He is that good.’

‘The team have shown a quick understanding of our businesses, and what is important to us.’

‘I have thoroughly enjoyed working with Alexandra Lopez-Cassero, who managed to explain complicated regulatory topics in a calm way, while keeping an eye out for pragmatic solutions. Brian Krobb is also worth a mention: responsive and always helpful in getting us across the finishing line of an M&A Project.’

‘Incredibly responsive and VERY easy to work with’

‘The Nixon Peabody team that works on our matters made the time investment necessary to truly understand the different sectors of our business and the associated unique legal considerations. They know our business, they know us, they know our concerns and preferences, and that makes them more than an outside law firm, it makes them a valued partner. Partner Tyler Savage and Associate Kat Murphy provide stand-out service and expertise. ’

‘What is unique is their capacity to answer any question in all domains but also to always take into account the needs of the business in assessing the risks.’

‘I work with John Partigan. Not only is John always available but it is really appreciated that as a partner he is the one to deal with all our issues so that he has a global view of our problematics. He has got a perfect understanding of our business and has a very wide expertise. ’

‘The Nixon team, especially Brian Krob, are true partners for us. They are responsive, balanced and thoughtful in their approach. We also feel that our in-house teams (both legal and business) learn and grow from working with Brian. In practice areas that are new to us, working with Brian and his team enables our in-house team’s professional development.’

‘Brian Krob is a great lawyer and true teacher. His ability to break down complex legal matters for our business teams and even in-house counsel coming into new practice areas is tremendously valuable for us as a business. The communication is always clear, effectively breaking down issues, educating in-house legal and business but then always offering clear advice.’
