John C. Rothermich

John Rothermich has been helping clients resolve critical business disputes and government investigations for over 20 years. As a litigator, John has obtained successful results in state and federal courts and before juries and arbitrators across the country in many kinds of cases, with a particular focus on fraud cases under the federal False Claims Act, trade secrets and unfair competition claims, complex contract disputes, corporate governance disputes, securities litigation, and trusts and estates disputes.

In the investigations context, John has helped clients respond to inquiries by U.S. Department of Justice, the U.S. Transportation Command, and various state agencies concerning alleged health care fraud, government contracts fraud, regulatory non-compliance, and antitrust issues. John also manages internal investigations to uncover and manage clients’ potential criminal and civil exposure or uncover possible trade secret theft. 

Although he has represented clients in a wide range of industries, John has particular experience serving clients in the healthcare, sustainable energy development, transportation, and technology sectors, including health care providers, insurers and laboratories, energy storage system manufacturers and developers, transportation and shipping companies, and software developers.

Whatever their industry, John partners with his clients to understand their business and develop a strategic approach to achieve their goals. John is dedicated to achieving optimal results for his clients, whether that means taking a case to trial, negotiating a compliance plan with key government regulators, or mediating a favorable settlement.   

After graduating from law school in 2000, John served as a law clerk for judges on the U.S. District Court for the Southern District of New York and the U.S. Court of Appeals for the Third Circuit. John subsequently practiced as a litigator for four years at the New York office of a major national firm, where his practice focused on defending financial institutions in fraud-related litigation and immigration pro bono matters.

A Westerner at heart originally from Salt Lake City, John moved to Portland in 2007. He then practiced as an associate and shareholder at a regional Pacific Northwest firm for 13 years. At that firm, John litigated several high stakes cases, including the successful defense of a government contractor in a US$250 million False Claims Act lawsuit and service as co-counsel for the Oregon Health Authority in its state false claims act claims against Oracle related to Oregon’s failed state health insurance exchange website. John also represented clients in connection with several criminal and civil government investigations, including federal antitrust inquiries and health care fraud investigations.

Since joining the firm, John has continued to help clients resolve disputes and investigations in a variety of industries, including victory in a two-week trial for a software developer on a multi-million dollar trade secret claim, an arbitration hearing for an anesthesiology practice regarding access to medical records, and an arbitration hearing for a battery supplier related to grid-connected energy storage facilities. John especially enjoys working closely with clients in the health care and sustainable energy development sectors.
