We have been using Guard Dog Storage since February 2026 as we moved from out of state and downsized some. Completing the rental agreement, initially, online was simple and April was very accommodating regarding key pickup. We have recently downsized to a smaller unit and Chris was exceptionally accommodating as we viewed options for our new unit and prepared to make the transition to the smaller unit. Our belongings have remained safe and dry for six and a half months and counting!

I recently went into Guard Dog Storage and rented a truck from them and April was so incredibly nice and made the entire experience a breeze! I’ve seen other storage facilities and this one looked well taken care of and secure, I’d absolutely rent a unit here if I needed it!

Recently I went a full month with my company service van in the shop and I was forced to rent cargo vans week after week. I initially went to Guard Dog for the rental simply because no one else had a cargo van available. But I kept coming back over and over again because of the amazing customer service! April, the girl at the counter, was incredibly friendly, helpful and patient. She smiled and chatted as she went EFFICIENTLY about her job. She went out of her way to help put me in another rental every time the mechanic failed to finish working on my service van. She helped me manage all the reciepts I accrued over that month. She’s amazing. April is the sole reason I kept coming back week after week. And she’s also the reason I now recommend Guard Dog to everyone I know. Thank you again April for making the whole experience so relaxed and easy.

Walked in off the street looking for storage. The team at guard dog storage was incredible. They had the perfect size unit for me and they even talked to me through the best insurance option for my needs. The on-site team was responsive and extremely helpful. Glad I found them! Highly recommend!
