Lamb McErlane has been in expansion mode lately, and on Tuesday the full-service regional firm announced it will operate its first office outside of Pennsylvania.

The West Chester, Pennsylvania-based firm has absorbed a seven-lawyer firm, Giannascoli & Thomas, which had offices in Exton, Pennsylvania, and Mount Laurel. As part of the linkup, Lamb McErlane will bring on three new attorneys, as well as the two offices, bringing the midsize firm’s head count to 47 and the number of offices to six.
