I recently moved in the area and was searching for a storage facility, I found this one and the manager Nancy was very helpful. She gave me a lot of info on unit sizes and prices. I left knowing I'd rent a pace from Fort Knox. I was sold on the knowledge and professionalism of Nancy. She's a good asset. Update I finally moved my furniture in storage. Everything was straight forward and the price is still reasonable. Nancy the owner continued to be helpful and walked me through the process with ease. I'm glad I decided to come back. ... Read more

I come to this facility on several occasions weekly and David, in the office is very helpful and has always been there to answer my questions and even helped me choose the right storage unit and even directed me in the right direction when I had water damage to my property inside of my storage unit. I do have a concern when it comes to the corporate office because David operates the office, I see him cleaning out storage units, cleaning the outside restroom, I see him showing people the different storage units at this large facility as well as handling the U-Haul rentals. I don’t understand how he is able to get all of his stuff done and still able to handle phone calls and returning phone calls in a timely fashion when he has so much responsibility when he is the only one working there. Myself as a business owner, I do not understand why they would have so much responsibility put on one person at this size of a facility especially when it comes to having to do paperwork and answering the phone. ...
