Spinning circle Big letter B

Brian Boyle represents financial services companies, including banks, trust and mutual fund companies, health care payers, and health and life insurers, in connection with class or mass actions. Drawing on his detailed knowledge of the business models of financial services providers, and his significant experience working with experts in economics and finance, Brian explains complex financial services products and services in ways that courts and lay juries can understand.

Bringing creativity and sophistication to opposing class certification, Brian focuses his practice on high-stakes disputes under the ERISA statute. He represents the employer/sponsors of retirement plans, as well as product and service providers to such plans, when the plans’ fiduciary committees are alleged to have caused the plans to pay excessive fees, select poor-quality investments, or engage in “prohibited transactions.” On the welfare plan side, he also represents clients in actions for health benefits and in cases by health care providers who purport to have assignments of their patients’ litigation rights under ERISA.

Brian also handles other consumer claims against banks and financial institutions, including claims by borrowers against mortgage originators and servicers and claims challenging fee structures under state consumer protection laws or the National Bank Act.

Brian is co-chair of the Firm’s Financial Services Practice and the Health Care and Life Sciences Practice. Brian also is active in the Firm’s Appellate Practice. Chambers USA and The Legal 500 have named him as a leading practitioner in the ERISA litigation and health care areas.
