Troy M. Frederick

Troy M. Frederick focuses his practice on helping catastrophically injured people.

Practice Areas

  • Wrongful Death
  • Industrial Accidents
  • Products Liability
  • Consumer Class Actions
  • Catastrophic Personal Injury
  • Motor Vehicle Accidents
  • Medical Malpractice
  • Dangerous Drugs and Medical Devices
  • Motor Vehicle Defects

Significant Cases

  • Mr. Frederick prepared and argued, in the Superior Court of Pennsylvania, the seminal case Shiner v. Ralston, 2013 PA Super 33, 64 A.3d 1 (Pa. Super. Ct. 2013), which established the Sudden Medical Emergency Defense for the first time in Pennsylvania. To learn more about this case please read the featured article in the April 5, 2013, Indiana Gazette.
  • Mr. Frederick scored a significant victory when the United States Court of Appeals for the Third Circuit vacated a district court’s order dismissing a proposed consumer rights class action lawsuit against Ambit Energy.  In Silvis v. Ambit Energy, et al., Defendant Ambit Energy is accused of charging exorbitant electricity rates and breaching its contract with Ms. Silvis and the Proposed Class by failing to set its rates based on the factors outlined in its contract.  Because of this significant victory in the Third Circuit, Ms. Silvis’ lawsuit will proceed with the goal of securing a just result for Ms. Silvis and thousands of potential class members across Pennsylvania. Troy M. Frederick, along with co-counsel Kohn Swift & Graf, P.C., represents Ms. Silvis and the proposed class. Read the entire opinion here.
  • Mr. Frederick is currently litigating numerous multi-state class actions, encompassing hundreds of thousands of people, against Electric Generation Suppliers for breaking their contracts with customers by overcharging them for electricity by more than 300% in some cases.
  • Mr. Frederick is co-counsel in a proposed nationwide class action/multidistrict litigation, filed in the United States District Court for the District of Colorado, against Air Methods Corporation and Rocky Mountain Holdings, LLC, related to alleged overcharging for emergency medical helicopter transport. In many instances, victims have been billed more than $47,000 for less than 100 miles of emergency medical helicopter transportation.
  • Mr. Frederick is lead counsel in a proposed class action lawsuit against REA Energy Cooperative, Inc. for refusing to return tens of millions of dollars of patronage capital to its current and former electric customers/members.
