Welcome to the ATD Valley of the Sun Chapter's Online Application Membership Portal

This online application allows you to make payments online for chapter memberships via Paypal or Debit or Credit card. You can also login to update your membership profile as needed.

To access a particular application, click the appropriate "JOIN US" button below. 

The types of applications available through this website are as follows:

  • Membership Application (Individual): Allows individuals to make online payments for 1 year chapter memberships such as a professional membership ($75), full time student membership ($30), or a volunteer membership ($45).
    Join Now (Individual)

  • Membership Application (Bundles): Allows organizations to make online payments for 1 year membership bundles of 5, 10 or 25. Organizational bundle memberships differ from individual memberships primarily in that they are transferable. For example, if you are the manager of training, you can purchase 5, 10 or 25 memberships (at a special rate) for all or part of the team. If someone leaves the team, the membership stays so you can simply reassign it.
