The expanding business community at the Riverwood Corporate Center along Highway J just north of I-94 in Waukesha County is an appropriate place for the new offices of the Michael Best & Friedrich law firm. A drive through the corporate park and nearby properties reveals some impressive names: Microsoft, Compaq Computer, MRA-The Management Association, Ameritech, Roundy's, Cobalt, GE Medical Systems, and Cisco Systems, and the American Cancer Society, among others. And more building continues - further evidence of the westward expansion of the metropolitan Milwaukee business community. Michael Best & Friedrich has completed a big leap into that expansion, recently opening its Waukesha County office in the Two Riverwood Place building of the corporate park. The downtown Milwaukee-based firm now has 22 attorneys (soon to be 23) at the Waukesha office, making it the largest law office in the county.
