"I'm very thankful for my role with Bi-State Development and the opportunity to lead public-private sector collaboration and uniting leaders from all modes of transportation, manufacturers, economic development organizations, elected officials and transportation agencies," Mary said. "This next phase of my career is another opportunity to work alongside talented colleagues and partners to help deliver infrastructure and strengthen the nation's infrastructure system."

Throughout her distinguished career, Mary has led nationally recognized transportation initiatives, secured support for transformative infrastructure investments, and managed complex programs that have enhanced mobility, economic growth, and quality of life across Missouri and Illinois.

As Illinois Regional Leader, Mary will provide strategic leadership and direction across Lochmueller’s Illinois offices, overseeing both the Central Illinois region, including our Champaign and Springfield offices, and the Southern Illinois region, including our Edwardsville and Belleville offices. She will also draw on her extensive experience in freight and intermodal transportation to support initiatives that enhance regional, national, and global supply chain competitiveness, advance freight mobility and strengthen critical connections between transportation infrastructure and economic development.

"Mary is one of the most respected transportation and infrastructure leaders in the Midwest," Scott J. Smith, PE, Vice President & Western Market Leader, said.
