Selected Experience

  • Supporting a lead expert working on behalf of a state Attorney General to assist in the evaluation of a proposed hospital merger, including evaluating potential conduct remedies.
  • Working on behalf of the Federal Trade Commission, provided support to the expert in analyzing the competitive effects of a Texas Medical Board rule requiring that physicians meet face to face with patients before offering certain services such as prescribing medication via telemedicine. The FTC closed its investigation after the State of Texas enacted a law that overrode the Texas Medical Board’s restrictive rules.
  • On behalf of Humana in connection with its proposed merger with Aetna, provided support for responses to the Department of Justice’s second request, analyzed likely competitive effects and barrier to entry and exit in the sale of Medicare Advantage products, and analyzed likely competitive effects in the sale of individual health insurance on public exchanges.
  • Supported testifying expert on behalf of the Federal Trade Commission in its proceedings seeking to block Cabell Huntington Hospital’s acquisition of St. Mary’s Medical Center in Huntington, WV. Conducted analysis showing that the proposed acquisition would substantially lessen competition in hospital services in the Huntington region, likely leading to higher prices and lower quality for patients.
  • Supported testifying expert in cases against major sports organizations for monopolization of television and internet broadcast rights to live sporting events. Modeled consumer demand for viewing sports broadcasts to quantify harm to consumers. The defendants settled prior to trial, offering expanded viewing options at discounted prices to consumers.
