About Us

Self Storage leader has been serving Spokane since 1994 with the opening of Argonne Montgomery Self Service Storage. In the fall of 2002 We opened North Cedar Drive In Storage to serve our Northside customers. Summer 2009 we expanded North Cedar with a state of the art building to better serve our customers.

Self storage leader is a family based company locally owned and operated.  We strive to provide the very best customer service and storage experience.
