Margaret M. Krumholz, president of Hauppauge-based Disc Graphics Inc., died Thursday, a week after suffering a brain aneurysm. She was 58.
 
Krumholz, one of the most prominent women executives on Long Island, joined Disc Graphics, a specialty printer, in 1994 as controller and rapidly moved up the ranks, said Don Sinkin, chairman of the board and chief executive. She became president 12 years ago.
 
“She had a work ethic that was incredible,” said Sinkin, yet managed to balance family life as well. “Nobody got shortchanged in Margaret’s life.”
