Learn More About Us


We started our storage business in 1999. It is a family-owned business and became our primary business when we closed Hanley Company in July of 2008. We started the business with storage units in Sun Prairie at 601 Commercial Avenue in 1999, added units in Windsor/DeForest at 4202 Reardon Road in 2000, then purchased aaa Secure at 713 Walsh Road in 2008. We changed the name from aaa Secure to A+ Storage and hired Gary as our property manager.

We started with regular cold storage buildings in Sun Prairie and added our first climate control building in 2015. We added the second climate controlled building in Sun Prairie in 2017. We added our climate control building at our DeForest property in 2018. Our Madison location had climate controlled buildings when we purchased the property. A+ Storage proudly expands its legacy with the acquisition of Parkside Storage in Sun Prairie, WI. We’ve seamlessly integrated A+ Storage – Parkside into our trusted network, implementing significant security enhancements to ensure the utmost protection for your belongings.

We keep our properties clean and strive to make things easy for our customers with easy payment options and great customer service!
