Director Processing

We need special materials to make the things we use in our lives every day. From cell phones, to jewelry to treating cancer, gold is one of these important materials. I started learning about gold in the country of my birth: South Africa, where I studied to become a chemical engineer.

Sr. Director of Quality

I grew up in a small farming community in Wyoming. I was the third of four kids, raised by a single mother. We were very poor. This forced me to be creative about how I completed projects in school. I used materials I found around my house and in the alley.

Central Region Bridge Leader

I grew up near Philadelphia, PA; went to college at Lehigh University where I earned a bachelor’s degree in civil engineering. Then I went to Purdue University to get a master’s degree in structural engineering.

Director Enterprise Architecture

I grew up in Texas but never owned a horse or a cowboy hat. I enjoyed camping and the outdoors which lead me as an adult to Colorado. I am a father of 4 children (and a dog named Taco).

President and CEO

The oldest of four children, Jill Tietjen grew up in Hampton, Virginia. She earned a BS in applied mathematics (minor in electrical engineering) from the University of Virginia and her masters in business administration from the University of North Carolina at Charlotte. She spent more than 40 years in the electric utility industry where she served as an expert witness and helped plan new power plants

Developer Educator

I’ve been writing code for most of my life and my favorite way to learn new tech things is to design and develop a game that will require that new-to-me tech knowledge to complete. I’m self taught with technology and studied World history in school because I find humans way more confusing than technology, and it helped a lot!

General Manager

When I was young, we moved around because my Dad was in the Army. I always liked school because that is where I made friends. I enjoyed learning math and science. When it was time to go to college, I chose Mine Engineering because I could use my math and science skills in a way that also let me spend time outside.

Associate General Counsel

I have been a lawyer for 30 years. I like to help solve problems, and work with engineers, geologists, environmental scientists, computer scientists and lots of people who know a lot about STEM. I am also a STEM cheerleader because my 20-year-old daughter is in college for math and physics

Director- Metallurgical Services

My name is Lauren Hafla. I collected rocks from a very young age. When I was 10, I began participating in Science Fairs and won the State of MT Science Fair in 8th Grade.

Principal Advisor

Meghan has over 12 years of experience in mine engineering. She has used software to create 3D designs of underground mines, developed the maps and instructions for drilling & blasting the rock, and worked closely with everyone to make sure the mining was carried out safely and efficiently.
