Meet the owner About SWi

I'm Mark Olson, founder of SWI Fence. After nearly three decades of fence building in Wyoming, I know the frustration of cheap materials and sloppy work. That's why our team makes it simple to get a fence that's strong, dependable, and built right the first time. My brother Alan and I built SWI on family values and craftsmanship - and today, homeowners, ranchers, and businesses across the state trust us to deliver fences that last. It's why SWI has become Wyoming's most trusted fence company.
