I joined Colorado School of Mines in the fall of 2013. I have 20 years of Environmental Health & Safety experience. Before joining CSM I was the Health and Safety Manager and Laser Safety Officer for the National Renewable Energy Laboratory (NREL) in Golden.

I joined the Environmental Health and Safety Department at Mines in August, 2016 working in the CSDF (Chem Store).  Before coming to Mines, I worked at the National Renewable Energy Lab characterizing solar cell materials.  While a far cry from FTIR spectroscopy, I totally enjoy the busy pace of the chem store, interacting with students and staff, and supporting other facets of the EHS department wherever I can.  Having lived in Colorado since the early 90s, I’m drawn to the outdoors but my early life in the Chicago area makes me a lifelong Cubs fan, of course!

Key Areas of Practice:

  • Chemical ordering, processing, storage
  • Chemical inventory management
  • Hazardous waste handling
  • Member of chemical spill response team

My previous experience includes 4 years of environmental compliance with a local government in Arizona and almost 6 years with the University of Colorado Denver as the Senior Environmental Health Specialist.

I hope to collaborate with faculty, staff and students to identify and understand these risks, and to develop procedures to ensure a safe work environment. When I’m not at Mines, you can find me playing basketball or at the climbing gym!
