    Mitch S. - 5 March 2026
    I needed storage at the very last minute on a SUNDAY this place was the only one I found that could actually accommodate me so I would be able to move in the same day. I made the reservation online and called not even 5 minutes later and Ryan was able to email me all the paperwork and get me signed in on the online portal. He walked me through everything! Really was a live saver. We were in the middle of moving to a new house only to find out we had been scammed so we had no where to take our stuff. These guys really came in and saved the day!! Thank you so much! ... Read more

    I have had no issues since renting my unit. I have been at the same storage facilities for over 12 years. Since Rocky States has taken over the place has done nothing but get better. I can always count Travis and the crew to answer any questions within the same day that I have left a message. When I have ran into income problems they have always been happy to help with rearranging my payments or moving my payment date to corelate with my pay check. I wouldn't rent anywhere else. I highly recommend Rocky State Storage to all my friends and family. Keep up the Great Job!! ... Read more
