Fortune 500 Support

O’Neill & Gaspardo provides unique intelligence. We have the resources and expertise to support or consult on any disagreements or litigation. Our team will set up a process to manage your project, conduct the financial analysis and provide the documentation to support the outcome. An example is a class action lawsuit. Our team provides the initial claims assessment and evaluates each one based on merit. We then advise the legal team on how to handle claims with a common probable outcome or individual claims that have unique circumstances. As needed, we consult with the legal team and provide our recommendations and financial details to support our insight.
