They handle high-stakes cases throughout the country and internationally, focusing their time, energy and skills to understand and satisfy both the litigation and the business needs of our clients.

Our commercial litigation attorney team aggressively and effectively represent clients throughout every phase of the litigation process, from pre-litigation counseling through discovery, trial and appeal, as well using alternative dispute resolution, when appropriate.  We use litigation not merely an end in itself, but as a method to deliver the best business solution to each individual client.
