Litigation

The moment a client calls us for help with a business dispute or litigation, we focus on our client’s ultimate goal.  At Sullivan, we shape our advice and strategies to our client's business realities, careful not to lose the business war while winning the litigation battle. We recognize that litigation is more than a legal issue for our clients — there are often major, complex business concerns as well.

Exploring creative legal options from the point of view of practical, commercial realities sets us apart. This strategic, holistic approach leverages our capabilities to help prevent budding disputes from turning into major crises.

When a negotiated resolution cannot be achieved, our early intervention and inventiveness strengthens our ability to vigorously litigate the dispute to a successful conclusion.

Regardless of the client or claim, we litigate each case aggressively yet efficiently and credibly, with lean staffing and hands-on partner focus and involvement.
