Representing The Full Range Of Whistleblower Cases

In Orlando, Tampa And Communities Throughout Florida

If you have uncovered evidence of corporate wrongdoing, you have the right to speak up. In fact, certain situations - known as qui tam - might entitle you to monetary compensation based on your efforts in holding your company accountable for fraudulent behavior.

Our firm can provide strong representation in a broad range of whistleblower cases, including those centering on the following:

  • Qui tam fraud
  • Medicare/Medicaid fraud
  • Defense contractor fraud
  • Oil and gas royalty fraud
  • Environmental violations
  • Knowingly selling defective products to the government
  • Subcontractor liability
  • Workplace safety violations
  • U.S. customs and shipping fraud

A whistleblower can be an employee, a former employee or even an individual with access to internal company documents. No matter your status or how you came to uncover the organization's wrongdoing, we encourage you to act quickly and contact one of our Florida lawyers.

What Is Health Care Fraud?

Health care fraud makes up a significant portion of qui tam cases. Our firm has the experience and legal knowledge to provide strong defense and protection from retaliation in cases involving:

  • Medicaid/Medicare fraudulent billing: These cases can include a broad range of offenses such as double-billing, neglect of services, standard of care violations and misrepresentation of credentials.
  • Anti-kickback claims: These cases typically involve a medical professional receiving anything of value - cash payments, merchandise, discounts, etc. - in return for referring a patient or ordering goods or services.
  • Best price/best value claims: These cases can include rebates given on pharmaceutical orders and discounts on health care equipment.
