We seek win-win solutions, and stand ready to promptly seek redress in Federal or State courts when required.  At the same time, we will exhaust all reasonable settlement avenues before suggesting litigation.  Both Shannon and Neil are admitted to practice at The Court of International Trade in New York City and numerous other Federal courts nationwide, including courts of appeal, as well as all Florida courts.
