Chicago-based Arnstein & Lehr has expanded its outpost in West Palm Beach by adding two partners and an associate, the firm said Thursday.

The firm added Neil Schiller, a municipal and government partner, from Becker & Poliakoff, and brought on environmental partner Matthew Coglianese from from Rasco Klock Perez & Nieto. It also added associate Eric Aaronson, who practiced with Schiller at Becker & Poliakoff following his work as a legislative fellow for U.S. Rep. Ted Deutch.
