The partners at Klafter Olsen & Lesser LLP founded their firm to bring the highest level of representation to contingency fee litigation to fight and prevail against the top defense law firms in the country. Together, the partners in the firm have obtained well in excess of $1 billion in recoveries for clients – be they businesses, shareholders, consumers, workers, tort victims or companies in bankruptcy who had claims for breach of duty against former officers and directors. We are selective about the cases we bring. And, unlike other firms that are too often constrained by hourly billing arrangements, we provide singular attention to all of our cases because our clients’ success is our success. The due diligence we perform before we initiate a case allows us to advise our clients early on as its strengths and weaknesses, and to aggressively focus the case from inception to a successful resolution through either settlement or trial. Our record speaks for itself. We also have an active appellate practice and our attorneys are often brought into cases just to argue appeals. Our attorneys have been recognized by courts and their peers time and again. There is no law firm in America or deep pocket entity that we cannot take on and succeed against. We have – and will – take cases through to trial and have successfully done so both in court and arbitral settings. And we will do so anywhere in America.
