Jerry A. Isenberg, 63, a partner at the Washington law firm Murphy & McGonigle, died April 24 at MedStar Washington Hospital Center. He lived in Cabin John.

He had complications after bypass surgery, said his wife, Rita Isenberg.

From 1975 to 2000, Mr. Isenberg worked as a lawyer at the U.S. Securities and Exchange Commission. He was the principal assistant director in the commission’s enforcement division from 1993 to 2000.

He was senior counsel at a number of Washington law firms, including LeClairRyan and Alston & Bird, before joining Murphy & McGonigle as a partner in 2010.

His professional awards included recognition last year as a top lawyer in securities regulation by Best Lawyers, a peer-reviewed legal publication.

Jerry Alan Isenberg was a native of Houston and a 1972 graduate of the University of Texas. He received a law degree in 1975 from the University of Pennsylvania, where he served on the law review. Shortly after graduating, he moved to Washington and began working at the SEC.

He was a financial supporter of the Symphony of the Potomac, a community orchestra.

Survivors include his wife of 31 years, Rita Plesums Isenberg of Cabin John; two children, Michael Isenberg of New York City and Elizabeth Isenberg of Providence, R.I.; and a brother.
