Recently, Ms. McIntyre has been at the forefront of defending nursing homes in matters arising from the COVID-19 pandemic, successfully devising and executing responses on behalf of firm clients since the earliest pandemic-related court actions were filed. She works closely with clients and claims professionals to invoke the protections of the Public Readiness and Emergency Preparedness Act (PREP Act) and other defenses to claims filed in jurisdictions nationwide. Similarly, she has led appeals in several circuit courts across the country, seeking to obtain the broadest possible protections for the firm’s clients. Ms. McIntyre also has served as embedded appellate counsel in pandemic-related cases involving nursing homes in various jurisdictions, successfully garnering amicus support in appeals from such significant groups as the U.S. Chamber of Commerce, the California Association of Health Facilities, and the American Health Care Association.
