What is your professional background and your role with Focus on Energy?

My work with municipalities and wastewater treatment facilities goes back to my days as an undergraduate student at Marquette University in Milwaukee, Wisconsin, when I worked for a municipality as part of the university’s co-op program.

I also worked for municipalities in various jobs for a few years after earning my bachelor’s degree in civil engineering. I then began to focus on wastewater treatment facility design and water systems. Toward that end, I earned my master’s degree in sanitary engineering and then joined an engineering consulting firm in their wastewater treatment facility design group. After that, I worked for a couple of consulting firms and focused on wastewater treatment and water systems, but basically focused on the wastewater side.
