ALPO Expanded Memberships Webpage

The ALPO Expanded Memberships were created in an effort to both support the Journal ALPO and raise funds for the ALPO Endowment. The purpose of the ALPO Endowment is to collect and grow money for the financing of a future headquarters of the ALPO. We invite interested members and non members to click on our PowerPoint presentation, The ALPO's Legacy or our brochure for further details concerning our future goal. Below are the classes of expanded memberships and the benefits of each class of membership. If you would just like to make a simple donation to the ALPO Endowment without the purchase of an ALPO membership, there is an opportunity to do that too. Of course, we greatly value our members who can only afford Regular, Sustaining, or Sponsor memberships. The option to purchase those classes of membership can be done on the standard ALPO Membership Page.
