Mandy Knight appointed chief of staff at Sanford Underground Research Facility

Every organization has individuals who seem indispensable—those with deep institutional knowledge, critical skillsets, and the unique ability to bring people and projects together for long-term success. Sanford Underground Research Facility (SURF) is fortunate to have many of these sorts of people–and all of them agree– Mandy Knight is among the best. 

In February 2025, Knight was officially promoted to chief of staff at SURF, solidifying a leadership role she has effectively filled for years. 

Knight, started at the South Dakota Science and Technology Authority (SDSTA) in January of 2008, after driving up to Lead from her home nearby, with her résumé in hand, to inquire about possible jobs at the newly formed laboratory.

“I just knew when the National Science Foundation originally selected the lab that it would be a great fit for me,” Knight says. “I came up the hill in Lead, parked in the parking lot, and thought, ‘Gosh, I hope I am in the right place,’” she added with a laugh. 

She was in the right place—and soon landed an interview and a job as front desk receptionist while providing administrative support to the SDSTA Board of Directors. Her responsibilities quickly grew from there. Within six months she became the administrative assistant and then moved on to executive assistant, senior project specialist, and eventually administrative services manager; a role she filled for 14 years before being appointed chief of staff. 

“Mandy’s long-term dedication and contributions to SURF’s success have been phenomenal,” said Mike Headley, SDSTA executive director and SURF laboratory director. “She is a key reason why we are a world-leading laboratory, and she is uniquely qualified to serve as our chief of staff. I am thrilled to be working with her in this new role.”

Knight came to SURF with a background tailored for the needs of an emerging research facility. She finished an undergraduate degree at Northern State University in biology and environmental science with an emphasis in business. Prior to landing at SURF, she worked in banking and insurance. On top of this, she and her husband, Chad, ran a successful business in Spearfish.   

“When Chad and I started our pub in Spearfish, it was a completely new venture for us. SURF felt similar to a startup, with that same kind excitement in Lead. Being part of something from the very beginning— helping to shape policies and build the framework—was a big part of what drew me here,” Knight says. 

Reflecting on her time at SURF, Knight acknowledges the incredible transformation the lab has undergone—from a fledgling research site with just ten employees to a thriving institution supporting cutting-edge experiments with a workforce of over 200. 

“I often heard people say that SURF hired the cream of the crop. We were fortunate to bring on top-tier infrastructure techs, engineers, safety personnel, and others from Homestake. They had lived and breathe this place for so long that they knew every nook and cranny. I feel a sense of respect for their experience and dedication. Their deep familiarity with the environment makes our operations safer for everyone,” Knight said. 

For Knight, the team of people at SURF and their wide range of backgrounds and experiences is a key part of the successes to date.  

“Everything comes back to our core values, which are all connected. In my view, the one core value that links them is caring for others. SURF has succeeded because of this extraordinary group of people—without them, this place wouldn't be what it is today.”

She is especially passionate about the lab’s impact on local communities, emphasizing the importance of fostering opportunities that allow talented individuals to build careers in South Dakota rather than seeking them elsewhere.

“When you think about it, Chad and I may not have stayed in South Dakota if it were not for SURF,” she said. “The success of the lab has been a really good thing for us—and for many other families.”

Looking ahead, Knight is excited for SURF’s continued growth. With major projects like LBNF/DUNE underway and future experiments on the horizon, she envisions the facility not only attracting top-tier talent but boosting the regional economy.

“SURF’s growth doesn’t just benefit the lab itself—it acts as a magnet for other businesses. New restaurants, hotels, shops, and technology companies are attracted to the area, diversifying the local economy. Increased activity drives further investment in local infrastructure, improving residents’ quality of life and stimulating spending. It’s a win for our community, and it helps the region thrive,” Knight said.
