About Us
As a family owned business, we take customer service very seriously.
Unlike our competitors, we don't raise rates every 45 or 90 days. We don't think anyone wants to be nickle and dimed. We believe that an important part of building a lasting rapport with our tenants is not raising rates every month or even every year. While rate raises may happen from time-to-time we seldom raise rates for tenants who have been with us for less than 18-24 months. Some of our competitors also require you to purchase tenant insurance.

I have been stressed out and anxiety-ridden, as I have had a life-changing event where I suddenly had to move.. So, I needed a small storage. Charlene was nothing but gracious and helpful. I had initially called her to see if there were open spaces - she told me yes and to come in. I came in to her office and she made everything so easy for me - minimal waiting, I moved in my things, signed paperwork, paid and done. I even had switch my unit to a bigger one the next day.. Charlene made it happen - no problems at all. You know how people can get - scoffy and short with you because you have "inconvenienced" them. This was the opposite. She was SO pleasant and made my life easier! Highly recommend - Charlene will take care of you.“

Horrible experience dealing with this company. The person running the storage site (Charlene) is a dimwit ditz. Not name calling just a perfect example of who this person is. She pulls the bait and switch routine shows me the spot for my RV. When I come to park my RV someone is in my spot. It's Sunday so office is close, so I call and leave a message. Monday rolls around no call back yet. Give them another call during business hours. No one picks up, I leave another message. Finally get a hold of her afternoon. She is completely oblivious to know who has parked there even thou she lives there has array of surveillance cameras at her office desk and supposedly has files on every vehicle parked there. She keeps telling me she will call me back but never does. After a week and no response I asked them to refund my money. Now waiting to see how long this will take.
