Leopold Gross represented me in a litigation that lasted several years and involved extensive motion practice, a trial, and ultimately an appeal. Throughout the entire process, he was prepared, strategic, and completely committed to getting the right result.In the end, he won the case in its entirety, including successfully overturning an improper ruling by the trial court on appeal. Watching him handle every stage of the case made it clear that he has a level of experience and skill that sets him apart. He's an exceptional trial lawyer and litigator who always seemed a step ahead.Just as importantly, he was straightforward, responsive, and someone I trusted during a long and stressful process. If you're looking for an attorney who knows how to litigate complex cases and see them through to the end, I highly recommend Leopold Gross.
