Genevieve Willens
Victoria and Tammy were so helpful! Super quick and easy. Would absolutely recommend.
Grace Harder
Best experience! Tami and Victoria were so nice, helpful and friendly!!!
Scott Moore
Always a pleasure! Very nice and easy to work with!
melanie
Very well kept, easy to work with, has great security, they went over and above to help us when we had furniture delivered and with anything that came up.
This is a great storage unit complex, it is very well managed and I cannot recommend highly enough.
Sarah Studer
I am clearing out my childhood home and procrastinated renting a storage unit as long as I could. Finally, I drove over, walked in and was greeted by two employees who showed me several unit options and helped me determine the right size (bonus: we got to ride in a golf cart to tour the units on their two properties that are a few blocks away from each other).

Once I had picked my unit, Tea helped me through the sign up process which could not have been easier! They also have tons of moving supplies like boxes, mattress and chair covers, etc that you can purchase at the office, and an onsite van that you can rent for a day to move your items (and it’s super affordable)!

All in all, something that I had put off for months took less than an hour to complete and now I just have to do the hard part of actually moving things into the unit.
Response from the owner:Hi Sarah, we are very happy to have provided you with such a positive experience! Thank you so much for choosing Guardian Storage!
Dylan Bialek
Super clean!
Response from the owner:Thank you Dylan!
stephanie selz
Tea is great!
Response from the owner:Thank you Stephanie!
Lee Ortenberg
Had a great experience storing my stuff here! The staff are very friendly and the units themselves are clean, easy to access, and secure! I do wish there were a few more parking spaces in the climate control area but I only ran into an issue once with this!
Response from the owner:Lee, we are so pleased you enjoyed your visit to Guardian Storage!
K Raynor
I’ve had a storage unit at Guardian Storage for my business for over five years, and I couldn’t be happier with the experience. Tammy, the manager, runs a tight ship with her husband keeping the grounds in top shape and her daughter Victoria providing excellent customer service. It’s truly a family-run operation, and you can feel the care they put into their work.

They’re always friendly, patient, and looking out for their customers, whether it’s keeping the property secure, answering questions, or making sure everything runs smoothly. Plus, the convenience is unbeatable—easy access, well-maintained units, and a hassle-free experience from start to finish.

If you’re looking for a reliable and welcoming storage facility, Guardian Storage is the place to go!
Response from the owner:K, thank you for your kind review; we are happy to pass along your comments to the team here at Guardian Storage!
