I joined Colorado School of Mines in the fall of 2013. I have 20 years of Environmental Health & Safety experience. Before joining Mines, I was the Health and Safety Manager and Laser Safety Officer for the National Renewable Energy Laboratory (NREL) in Golden. Previously, I held similar positions with Eastman Kodak Company and COBE Cardiovascular. The EHS Department’s current focus is on increasing EHS training offerings to the campus and helping evaluate and control risks associated with the work we do. I am a huge proponent of collaboration and learning. I believe in a risk and fact based approach to health and safety, rather than a black and white compliance mindset.

I joined the Mines’ EHS department in March 2022.  During my 15 years of experience in the environmental industry I’ve worked on superfund sites, hospitals, and hazardous materials companies creating chemical safety programs and hazardous materials management.  Prior to joining Mines I  worked as a science teacher in middle and high schools for 8.5 years.  My passion for chemistry and safety continues in this role as safety starts with the understanding of chemistry, the safety and responsibility of hazardous materials.  When I’m not here at Mines I’m easily found hiking, skiing, enjoying a good book, German soccer (Go Bayern Munich!), or with my family and am easily distracted by conversations of chemistry and traveling.  I look forward to supporting faculty, staff, and students with chemical safety in both ordering, storage, and disposal.
