Patric Hooper

Founding Partner

“Serving clients well as a litigator involves more than aggressive court representation. It often requires seeing beyond the four walls of the courtroom to find the most pragmatic solutions elsewhere, resolving matters in a way that best protects our clients’ legal and business interests.”

With a combination of skilled and creative courtroom advocacy, deep industry knowledge, and practical insights that can only come from decades of experience, Patric Hooper has established himself as one of the country’s most accomplished health care litigators. Called upon by clients across the health care spectrum to handle their most complex and consequential matters, Pat has obtained favorable outcomes and defended his clients’ interests in hundreds of high stakes, high-profile judicial and administrative proceedings involving fraud, abuse, and False Claims Act allegations. 

A founding partner of Hooper, Lundy & Bookman, Pat is a hands-on trial lawyer who also understands that the optimal resolutions for his clients don’t always involve a jury verdict or court judgment. Leveraging his comprehensive knowledge of health care law and his productive working relationships with regulators, Pat can craft pragmatic solutions that protect his clients’ interests while avoiding prolonged and expensive litigation. As the government’s posture in fraud, abuse, and False Claims Act cases has become increasingly aggressive, Pat’s years of experience provide a steady hand to clients who find themselves in the government’s crosshairs. 

Pat represents clients in every sector of the health care industry, including hospitals, clinical laboratories, physicians, and manufacturers of medical devices. Chambers USA remarks that Pat “retains his standing as a leading health care litigator. He frequently acts on large-scale actions, reimbursement disputes, and licensing issues on behalf of both for-profit and nonprofit entities.” His clients appreciate not only the results he obtains on their behalf but also his responsiveness and accessibility. 

A seasoned appellate advocate as well as trial lawyer, Pat has been involved in some of the most important and complex Medicare, Medicaid, and CHAMPUS (TriCare) matters, as well as state anti-rebate and referral disputes.

Pat began his legal career with the California Department of Justice in 1973. As a Deputy Attorney General, he represented various state agencies in civil litigation involving health, education, and welfare matters. Since entering private practice in 1976, he has amassed an impressive track record of success and earned the trust of countless health care clients facing federal or state investigations, litigation, and other proceedings.

Congress amended the AKS as a result.
