It started with a passion for rocks...

  • ...and an amazing professor at Lawrence University in Appleton, Wisconsin. It took me to the University of Florida for a master’s degree then back to Chicago, to my roots. I’ve spent the better part of two decades guiding engineers, architects, and builders through state and federal regulatory mazes. I give peace of mind to banks and commercial lenders that their investments are safe from environmental risk. I test and clean soil and groundwater to keep people safe from toxins that unfortunately get spilled from time to time. I love my career because it gives me the opportunity to make a positive impact on the environment and the world around me. I look forward to working with you on your next project.
