Bruce Hill, RCDD, LEED®AP  President

As the person in charge of the company’s commercial construction division, Bruce gets plenty of practice helping clients and team members solve issues that come up on a daily basis. No wonder more customers appreciate his willingness to be a problem solver, than just a problem identifier. It’s just one of the skills he has honed during a 20 plus year career in the electrical design field. Known for his ability to work with people, Bruce focuses on making sure things are done right, a skill that doesn’t happen without doing his homework on a regular basis. For Bruce and others at Yellowstone Electric, the philosophy of “what’s right for the client” drives daily decision-making. Yes, he’s grateful for the wisdom and knowledge gained from a distinguished career. But ultimately, focusing on people and their well-being continues to matter to Bruce more than anything else.

George Haddenhorst
Director of Business Development Hydro-Division

Even as George Haddenhorst spent nearly two decades with Conoco Phillips, he never forgot his ties to Billings and Yellowstone Electric – where he had worked early in his career from 1977 until 1985. So when given an opportunity to rejoin Yellowstone Electric as a co-owner and vice president in 2003, it seemed like a natural career move for George. But George envisioned something greater, a chance to take a strong and stable company into a new era, and a chance to leave a legacy. Back at Yellowstone Electric in a leadership position, he helped enhance the company’s capabilities in the industrial side of the business and spurred a push to innovate in new technologies. George became president of Yellowstone Electric in 2006, emphasizing the company’s commitment to operate completely from a foundation of honesty and integrity. It’s a commitment that has resulted in more repeat business from existing clients. As president, George remains focused on moving the company forward while providing its clients with leadership going into the future. “We’re not afraid to embrace change,” George said.
