Today, we welcomed medical students from CU Medicine to Ralston Quarry for a firsthand look at the mining industry and its connection to public health.
The tour came together through coordination with the Colorado Division of Reclamation, Mining and Safety (DRMS), whose representative also joined us for the visit. Rich DiManna, Colter Hines, Kevin Keyser and Justin DiManna led the group through various areas of the quarry and shared their knowledge and experience along the way.
We appreciate the opportunity to connect with future medical professionals and give them a closer look at our industry.
