Sheryl Filby Williams

Vice President, Hydrogeologist

Though she didn’t know it at the time, Sheryl Filby Williams made a career-changing decision in college.

"I’d always been interested in science and engineering, and I was focusing on physics during college. But then I took a geology class and it was a perfect fit." Sheryl, then a student at Gustavus Adolphus, found herself fascinated by the processes that mold the earth’s landscape, rivers and glaciers. And field research appealed to her outdoorsy side.  In graduate school, Sheryl was able to combine the study of geology and water by focusing in hydrogeology.

Her decision to pursue a career in geology and hydrogeology came naturally: environmental science combined her love of the outdoors – she’s an avid biker, hiker and camper – with a passion for problem-solving.

And as one of Barr’s senior hydrogeologists, Sheryl gets to solve a lot of problems. In collaboration with her colleagues, she studies and resolves environmental challenges for cities, watershed districts, and  industrial clients. For more than 15 years, she’s worked on everything from wind turbines to wellheads. What she enjoys most about her work is the variety: "Some days I’m wrapped up in an incredibly technical puzzle. The next day I’m trying to figure out how to best satisfy a client’s complex needs. The work is always changing."

Away from work, the native Duluthian enjoys spending time outdoors with her husband and two young children.
