White Plains firm DelBello Donnellan Weingarten Wise & Wiederkehr has added six lawyers from a smaller firm whose managing partner is expected to join the federal bench.

Lawyers from Collier Halpern & Newberg, co-founded by Philip Halpern, joined DelBello Donnellan this month, bringing about $4 million to $5 million in business and new capabilities in litigation and corporate work, according to DelBello Donnellan’s managing partner, Al Donnellan.
