For the third time in the last year, Dilworth Paxson has lost a practice group leader only to replace the lawyer with a young partner from another firm.

The latest bit of movement involves Joel Friedman, the white-collar litigation practice group leader, who left to form a partnership with solo practitioner Richard Levan. David Laigaie — formerly a partner at Miller, Alfano & Raspanti — replaced Friedman at Dilworth Paxson’s Philadelphia office.
