Y. Michael Twersky concentrates his practice primarily on representing plaintiffs in complex litigation, including on insurance, antitrust, and environmental matters.

In the past, Mr. Twersky has worked on a wide variety of insurance matters including an insurance case in which a Federal District Court found on Summary Judgement that a large insurance company had breached its policy when it denied benefits under an accidental death insurance plan. Mr. Twersky has also worked on a number of antitrust class actions alleging that pharmaceutical manufacturers wrongfully kept less expensive generic drugs off the market, in violation of the antitrust laws, including: In re Skelaxin (Metaxalone) Antitrust Litigation, 1:12-md-02343 (E.D. Tenn.) ($73 million settlement in 2014), and In re Solodyn Antitrust Litig., 14 MD 2503 (D. Mass.) (combined settlements in excess of $76 million in 2018). Mr. Twersky has also represented inmates in connection with allegations that various inmate calling services charged unreasonable rates and fees in violation of the Federal Communication Act.

Currently, Mr. Twersky is litigating a number of complex class actions related to insurance products, including proposed class actions in multiple forums against a workers’ compensation insurance company alleging that the company deceptively sold illegal workers’ compensation programs that were not properly filed with state regulators. E.g., Shasta Linen Supply, Inc. v Applied Underwriters et al., No. 2:16-cv-0158 (N.D. Cal.). Mr. Twersky is also involved in a proposed class action in Federal Court brought on behalf of Alaska-enrolled Medicaid Healthcare Providers against the developers of the Alaska Medicaid Management Information System Company alleging that providers were harmed as a result of the negligent and faulty design and implementation of the MMIS system. See South Peninsula Hospital et al v. Xerox State Healthcare, LLC, 3:15-cv-00177 (D. Alaska). Mr. Twersky is also involved in environmental litigation on behalf of various states to recover the costs of remediation for contamination to groundwater resources.

Mr. Twersky graduated from Temple University Beasley School of Law in 2011, where he was a member of the Rubin Public Interest Law Honors Society and a Class Senator. In addition, Mr. Twersky advised various clients in business matters as part of Temple University’s Business Law Clinic.
