Robinson Cole LLP
High Contrast Mode

Patrick W. Begos is a trial and appellate lawyer who has represented administrators and insurers of life, health, and disability benefit plans for more than 30 years. His clients include many of the largest managed care organizations in the country, as well as the largest insurers of group life and disability benefits. Pat has litigated hundreds of ERISA benefit and retirement fund disputes in courts around the country, including dozens of appeals. Pat also regularly defends non-ERISA claims for group and individual benefits. He co-chairs our firm's Managed Care + ERISA Litigation group.

Pat’s extensive and long-term participation in the field has allowed him to help guide the evolution of ERISA claim procedures. He prevailed in a key ERISA case, Heimeshoff v. Hartford Life & Accident Insurance Co., which went to the U.S. Supreme Court and resolved a national issue over the enforceability of time limits on an individual’s ability to sue for benefits after being denied. He has also counseled clients on implementing appropriate claim processes to conform with ERISA’s complex and often confusing regulatory scheme.

Pat has always approached litigation as a way of resolving underlying problems, rather than an end in itself. This practical focus leads to development of bespoke strategies to help his clients achieve their individual goals in the most efficient and cost-effective manner.

Pat is a regular speaker on life, health, disability, and ERISA litigation topics, and has written extensively on benefit litigation for various nationwide publications.

Commercial + Business Litigation

Pat also has broad experience as a trial lawyer representing plaintiffs and defendants in diverse commercial and business litigation. He has represented clients in cases with high financial stakes, such as a feud among several countries over ownership of $70 million in Roman silver, claims regarding defective nuclear power plant components, and a $23 million breach of contract dispute.
