Practice head(s):

Paul Khoury; Scott McCaleb

Other key lawyers:

Jon Burd; John Prairie; Tracye Howard; Samantha Lee; Tara Ward; Kendra Perkins Norwood; Rand Allen


‘The Wiley team approaches Federal Procurement law with the proper balance uniquely attributable to our field. Government contractors have to balance protecting legal rights with (and sometimes against) the largest customer in the world under a regime of highly complex and sometimes conflicting regulations. It can be easy to apply a general or unilateral “zealousness” to advocacy in our world, but the white glove balanced approach offered by the Wiley team strikes the right balance necessary to survive in our field. Few firms offer that approach effectively. My advice to other in-house counsel would be to strongly consider the above in making your decision for representation.’

‘Tara Ward is our partner of choice, although the bulk of the Wiley team stands head and shoulders above the dozens of attorneys I have worked with in the past . Tara is a once in a generation legal mind, combined with the humility and poise to navigate the complexities of the challenges facing her corporate clients.’

‘Wiley has great background in government contracts. They give practical advice on complex issues.’

‘Responsive, good rates, willing to write off time where there’s a need for a large team due to bandwidth.’

‘Great comprehensive approach to client needs.’

‘Highly qualified and excellent client service; very responsive.’

‘The team focuses on government contracting. They look at all aspects of government contracts. I find that Wiley lawyers provide a deep knowledge of government contracting expertise based on research and also on knowledge from experience based on the wide variety and history of matters that they have worked on.’ 

‘John Prairie is always available to help out. John understands how to brief top management. He has a calm, certain demeanor that instills confidence from the business that he knows the answers rather than guessing.’
