The Northeast, Maine, and New Hampshire Self Storage Associations are hosting a joint 2-day virtual education event on November 4th & 5th. With the cancellation of their fall shows, the associations are teaming up to provide education to their members and their state self storage industries.

Rather than dwell on what should have been, we are determined to look forward to the coming year, opportunities, and possibilties. Let’s look ahead and learn what processes, regulations, trends, and technology can help you succeed in the future.

Check out this event and register today here!  Register for Forward 2020
