Cooley has bolstered its mid-Atlantic ­presence, as well as its life sciences and ­international arbitration abilities, with the addition of six partners from the Philadelphia suburbs and New York.

Cooley’s life sciences practice added partners Jeffrey Libson and Geoffrey Starr from Pepper Hamilton’s Berwyn office, as well as Manya Deehr, a founder and ­principal at Life Sciences Law Group, a small firm with offices in Newtown, Pennsylvania, and Highland Park, New Jersey. New York will be the primary office for all three, although they will be working on life ­sciences matters in various locations.
