12-31-2025Dan has been a tremendous help to me and if it wasn't for him I wouldn't have been with the storage as long as I have. He's been extremely accommodating very very helpful and the storage units were always very clean and stellar. Everything was always immaculate when I was going to try to check out my storage and I want to thank you all for hiring that man. I believe that he should own his own and if not be given a major major raise and that he's a valued v person for the storage unit company and also I'm so grateful for all of his personal help and his help with me through my transitioning thank you so much take care happy New Year Dan healthy and happy and prosperous for you and your family.
