Jeremiah Cullison
If you’re looking for secure, reliable storage in the Boulder, Superior, Lafayette, Louisville, or Broomfield area, stop scrolling. Guardian Storage in Superior is it.

I’ve used storage units in half a dozen states, and nothing has come close to the experience I’ve had here. It’s clean. It’s safe. It’s actually affordable. But what really makes this place shine is the people. Especially Sam.

Sam is the kind of guy you want on your team when you’re juggling a move, navigating a life pivot, or just trying to keep your stuff from becoming someone else’s problem. He’s sharp, down-to-earth, genuinely funny, and totally on point. You can tell he’s done this before. He brings real knowledge and calm energy to the chaos that usually comes with moving.

Each time I came in, whether I was a mess or just needed a quick question answered, Sam treated me with respect, professionalism, and kindness. He makes the process feel easy. His coworkers were also friendly, present, and ready to help. Shoutout to the whole team for being solid humans.

And let’s talk about the business center for a second. It’s actually useful. Fast Wi-Fi, comfortable seating, and amenities you don’t expect at a storage place. I’ve even worked remotely from there mid-move. It’s that good.

Bottom line: If you need a top-rated, climate-controlled, secure storage unit near Boulder or Broomfield that’s well-run and staffed by genuinely helpful people, Guardian Storage in Superior is hands down the best self-storage experience I’ve had in Colorado. Whether you’re downsizing, moving, or just need extra space, this place delivers. Ask for Sam. You’ll walk away impressed
