Ryan’s Comment on the Role of Litigation

“I view litigation as an opportunity for our clients to define and preserve their legal rights, and as a process that can help advance rather than impede their objectives.  Every successful case involves listening to our clients, understanding their priorities, and weighing the opportunities and benefits of each development throughout the case. Helping a client achieve his or her goals is really how we define a litigation victory.”
