Norman L. Reimer, who stepped down in May as president of the New York County Lawyers’ Association, where he led a long and successful effort to reform the state’s indigent defense system, has begun work as executive director of the National Association of Criminal Defense Lawyers in Washington, D.C.

Reimer, who has lived within three blocks of New York University since the 1970s, when he earned his bachelor’s degree and J.D., flew to the capital on Thursday to hunt for an apartment and meet with the 20 administrative staffers who serve his new organization’s approximately 13,000 members.
