    Searching for a storage unit can be stressful. Many storage companies have a lot of fees, contracts and high monthly fees. I did research online and came across Extra Space Storage in Ontario, CA. Jeff (Store Manager) was very professional and kind over the phone and in person. Jeff took the time to understand our needs and showed us 3 units to ensure we selected the right unit. Extra Space Storage offered such low month to month monthly fees. The facility is very clean and organized. Thank you, Jeff!

    Lauren is truly amazing and was able to help me immensely. Needed access to get my Military Uniform for a ceremony, and she was there to the last minute helping me when I needed it most. Every time I visit my storage I hope I see her and say hello. She is always working hard!!!!
