MILWAUKEE – GRAEF, an engineering, planning and design firm headquartered in Milwaukee,
Wisconsin has announced its transition in leadership of the Milwaukee Transportation Group from Burt
Naumann to Mary Beth Pettit.
Naumann, who has been with GRAEF for 40 years, will shift his focus to GRAEF’s nationwide
transportation market. In 1995 he was named leader of the Field Services group (construction services and
survey) and in 2000 was named leader for Field Services and Transportation. His new role now includes
oversight of the newly opened Miami office in addition to his already active oversight of Orlando, Chicago-
O’Hare, and Green Bay offices.
“Burt’s commitment to his clients and invested interest in the growth of the company has proven him an
invaluable leader within the firm,” said John Kissinger, President and CEO of GRAEF. “We are very
excited to see Mary Beth take over the leadership of this team — her expertise in an array of transportation
projects is only one reason she will be a great fit in this role.”
