The merger that formed Day Pitney seven years ago has turned out to be far from a smooth marriage. The Northeast firm has lost key partners over the years, the most recent a five-partner real estate transactional group that left in 2013. Last year’s headcount dropped by almost 14 percent from 2012, even as firms on the NLJ 350 survey overall saw a 3.9 percent increase in their numbers of attorneys — the biggest gain since 2007.

Managing partner Stanley Twardy Jr., in an email to the NLJ, said, “Similar to other firms nationwide, we continue to reshape our staffing to better align with industry norms and changing client requirements, and this was the case with the departures last year.” He declined to comment further.
