I’ve known Ralph before the acquisition or acquiring of the old storage company. He’s always done a great job and I understand why he is still there and a valued member of y’all’s team. He’s understanding and kind. Every time I’m there, he’s out and about taking care of the property and building. Great relationships with the renters.. He has came by and Interacted with us as I was at the storage with my kids. He has walked around with my kids, showing them different storages and teaching them things.

Response from Extra Space Storage (3/6/2026)

We are excited to hear Ralph continues providing excellent service, James! It's wonderful to know that Ralph's commitment to excellence has remained consistent even through the transition from the previous storage company. We truly value team members like Ralph who go above and beyond in their daily responsibilities, whether it's maintaining the property and building or taking the time to interact meaningfully with our renters and their families. His kindness and understanding, along with his willingness to engage with you and your children during your visits, perfectly exemplify the type of personal service we strive to provide. Ralph's approach to building genuine relationships with our renters is exactly what sets our facility apart.
