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.”

Pettit is transitioning into the role of Milwaukee Transportation Group Manager by internal election as of August 1. She has 23 years of experience with GRAEF and was named a Principal of the firm in 2006. Prior to this transition Pettit was a project manager and a public involvement specialist for arterial and freeway projects in urban areas.
