Today we decided to go with ExtraSpace Storage for our storage needs. The manager, Dashten Holloran was so helpful in finding us a storage unit that would perfectly fit our needs. He gave us a tour of a couple units and we decided on the 10x15. We would highly recommend this storage facility to our friends and family because of the convenience, cleanliness and how professionally it is ran.

Thank you for your wonderful feedback, Steve! Dashten and the team will love hearing this. We look forward to serving you!
