Peterson Sullivan Acquires Anderson ZurMuehlen Seattle Office

Peterson Sullivan (FY09 net revenue of $14 million), Seattle, acquired the Seattle office of Helena, Mont.-based Anderson ZurMuehlen & Co. (FY09 net revenue of $21.7 million). The two Seattle firms will operate as Peterson Sullivan LLP effective Nov. 1. (13 partners, 100 staff).

“This joining of practices is an exciting step for our firm, and we found an ideal fit in Anderson ZurMuehlen,” says Chris Russell, partner at PS.

“We’re looking forward to beginning this new chapter as PS,” said Joe Wilcynski, VP of AZ’s Seattle office.

AZ partners Joe Wilcynski and Rob Keasal will become partners at PS, and are two of the 10 AZ staff joining PS.
