Board of Directors

Kathryn Perszyk is the Director of the Land Protection & Revitalization Division at Virginia’s Department of Environmental Quality (DEQ), and oversees the agency’s Remediation, Petroleum Storage Tank, and Solid and Hazardous Waste Programs. Kathryn joined DEQ in 2006 as a regional solid waste compliance inspector, before moving on to other roles at DEQ in solid waste permitting, guidance, and regulatory development, before becoming the Division Director in 2021. Prior to joining DEQ, she was a consultant working in the areas of air permitting and emissions reduction. She holds a BS from Georgia Tech in Chemical Engineering.

Kathryn has also been an active member of ASTSWMO for over a decade. She initially joined ASTSWMO as the Region 3 representative on the Solid Waste Disposal & Conversion Task Force and later served as the Vice-Chair and Chair of the Task Force as well as on ASTSWMO’s Coal Combustion Residuals Ad Hoc Workgroup. She recently served as Chair of the Materials Management Subcommittee, with her term ending October 2024.

Christine Sieger joined the Wisconsin DNR’s Remediation and Redevelopment (RR) program in 2013 as the administrator of the Ready for Reuse loan and grant program. In 2014 she became the Brownfields and Outreach section manager, and in 2018 she took on the role of RR program director. On her watch, the RR program oversees emergency spills and the investigation and cleanup of environmental contamination at sites under state authority, Superfund, LUST, RCRA Corrective Action and at federal facilities. RR also includes a robust brownfields program which has assisted with the redevelopment of several thousand contaminated properties.

In October 2022, Christine was honored to join the ASTSWMO board as the Region 5 representative. She was a member of the board’s finance and strategic planning committees and served as one of two board liaisons to the CERCLA and Brownfields Subcommittee. She knows she’s given back only a fraction of what ASTSWMO has given to her.

Christine spent the first 11 years of her professional career as executive director for the non-profit partner to the National Park Service for the Ice Age National Scenic Trail, during which she served on the boards of American Hiking Society and Partnership for the National Trails System. A 7-year stint in the private for-profit sector followed, where she gained valuable experience that she brought to her job at the DNR.

Christine has a bachelor’s degree in anthropology from the University of Wisconsin-Milwaukee and received her master’s degree in urban and regional planning from the University of Wisconsin. She is a mom to three kids and a rescue dog from Texas, and a wife to her musician husband. She loves road trips to national parks and is seldom found without a needle and thread and at least one knitting project.

Suzanne Engels is the Administrator of the Solid and Hazardous Waste Division of the Wyoming Department of Environmental Quality (DEQ). Alongside a talented staff, Suzanne regulates the storage, treatment, and disposal of municipal solid waste, industrial waste, and hazardous waste throughout Wyoming. Suzanne also oversees environmental remediation projects and manages the Underground Storage Tank Program, which addresses environmental impacts and returns contaminated properties to productive use.

Suzanne has served DEQ since 2008 in various roles within the Solid and Hazardous Waste Division and the Water Quality Division. Before joining the State of Wyoming, Suzanne worked for the Colorado Department of Public Health and Environment in the Water Quality Control Division and for the City of Englewood at the Littleton/Englewood Wastewater Treatment Plant. She also had short tours with the US Fish and Wildlife Service and the US EPA Region 8. Suzanne’s past ASTSWMO involvement includes serving as the Vice-Chair for the Solid Waste Disposal and Conversion Task Force within the Materials Management Subcommittee and as the Region 8 Representative on the Board of Directors.

Suzanne earned her Bachelor of Science degree in Environmental Science and Computer Science from Regis University and her Master’s degree in Environmental Science and Engineering from the Colorado School of Mines. Suzanne resides in Cheyenne with her husband, three children, one dog, and six chickens. She enjoys all types of outdoor activities with her family including camping, canoeing, hiking, and fishing.
