Heidi has over 21 years of experience in site assessment and cleanup activities at a wide variety of urban facilities and rural properties.

One of Heidi’s strengths is helping clients manage their environmental liabilities through the project life cycle.

Fun Facts

Heidi previously had a career in Human Resources with her Business degree. She and her husband relocated from the Northwest to Wisconsin for 10 years, where she became a Geologist. They have been back home since 2005, and she has recently taken up photography to document the beautiful scenery we get to enjoy every day. Heidi grew up on Puget Sound, and having the blend of mountains and sea is what makes her happy.
