About Us

Northern Door Storage is a combination of passions for the Bierman family. Their knowledge of mini-storage and love for Door County provides a way for them to provide a service for the residents and visitors to the area.

Born and raised in Ephraim, Wisconsin, right in the heart of Door County’s picturesque northern peninsula, owner Rich Bierman is no stranger to the unique needs of Door County living. While he and his family settled down in nearby Green Bay, Wisconsin, they still reside in Door County all summer and very frequently throughout the year, and remain active in the local community.

Rich and his wife, Karen have been in the mini-storage business for more than 15 years and are available and willing to help you with whatever your storage needs may be. Whether it be choosing the right storage unit for your items or giving practical tips on how to effectively winterize your vehicle for storage, they’ve been there, done that, and are happy to share their knowledge with you.

The Bierman family are avid boaters and can often be found at the Ephraim Yacht Club, where they are active volunteers and members. They’re also involved with the Ephraim Historical Foundation, belong to the Sister Bay Advancement Association, and can often be seen on their boat traveling to Door County’s “hot spots”.
