The Twin Cities, home of the Mall of America, might now also be Law Firm Mergertown, USA.

Gray Plant Mooty, Minneapolis’ oldest continuing law practice, announced this week its acquisition of Hughes Mathew Greer, a three-lawyer firm based in nearby St. Cloud, Minnesota. The union is the latest legal services combination in the land of a thousand lakes, coming a week after Ballard Spahr agreed to absorb Minneapolis-based Lindquist & Vennum, the second merger in two weeks for the Philadelphia-based Am Law 100 firm.
