A former health care fraud chief at the U.S. Attorney’s Office in the Eastern District of New York has joined a Long Island-based firm to lead its practice representing clients in the industry.

Kenneth Abell, who spent the last 10 years at the Eastern District prosecutor’s office, joined 95-attorney firm Abrams Fensterman, Fensterman, Eisman, Formato, Ferrara, Wolf & Carone this month as a partner and head of its health care fraud and white-collar criminal defense group. To his knowledge, he said, he is the first former federal prosecutor from the Eastern District to join the growing firm.
