    Staff was very thorough in providing the right size unit for my belongings and the best deal for my short term rental. Dennis, the manager is the person I worked with, highly recommended.

    After a rough start elsewhere, Extra Space Storage exceeded expectations. Though day one had gate issues, day two was exceptional. Dennis’s professionalism truly stood out. He personally helped ensure I had access, checked on me, and when he noticed I dropped something, he carried it all the way to my unit. On top of that, he provided a credit for the inconvenience. His kindness, respect, and willingness to solve issues made it a truly outstanding experience!

    I rarely take the time to write reviews, but Dennis Brunner truly deserves recognition for the exceptional level of service he provides. From start to finish, Dennis demonstrated professionalism, knowledge, and a genuine commitment to helping others. His attention to detail, clear communication, and willingness to go above and beyond made the entire experience seamless and stress-free. What stood out most was not only his expertise, but his character. Dennis treats people with respect, patience, and honesty—qualities that are increasingly rare in customer service today. He took the time to ensure every question was answered and every concern was addressed, making me feel confident and valued throughout the process. It’s clear that Dennis takes great pride in the work he does and in the way he represents his organization. Professionals like him set the standard for what outstanding customer service should look like. I would highly recommend Dennis Brunner to anyone looking for someone dependable, knowledgeable, and genuinely dedicated to helping people. An absolute pleasure to work with and a true professional. ⭐⭐⭐⭐⭐ jomelbin silvestre.
