Aaron Krauss is a member of Cozen O'Connor who practices in the Commercial Litigation Department in the Philadelphia office. He concentrates his practice on business litigation, labor and employment litigation and intellectual property litigation. Aaron has practiced at Cozen O’Connor since 1998.

Aaron tries cases in both state and federal court and before arbitration panels on behalf of companies (or officers, directors or shareholders of companies) who have disputes with other companies or shareholders. These disputes usually arise out of a prior business or employment relationship. Although clients always want to win their case, Aaron recognizes that business goals must remain paramount, and a victory that comes at too great a cost either in terms of dollars spent or the harm to an otherwise important relationship is at best a pyrrhic victory. As a result, he provides practical advice recognizing that the lawsuit he is handling is only a part of a larger whole.
