Nathan Assor doesn’t like to call Golenbock Eiseman Assor Bell & Peskoe a boutique. The New York-based firm may have just 50 lawyers, but Assor is quick to point to its rounding of practices akin to what a large firm might house, minus the extra layers.

“You work with us, you tend to get a lawyer who has big-firm training and is intimately involved,” Assor said. Back in 1982, the corporate lawyer co-founded the firm alongside two other former associates at Kramer Levin Naftalis & Frankel. In the corporate arena, the firm has built a niche in middle-market mergers and acquisitions, often for private equity funds.
