PASS Member Engagement Campaign

Stay tuned for updates on the Local Groups’ progress over the next few months!

Questions? Contact: CommunityTeam@pass.org

From March 1st until May 31st, 2017, PASS will be supporting Local Group Leaders to engage with existing PASS members, as well as encourage new members to join Local Groups.

Our aim is to increase awareness of PASS as an organization, as well as the associated learning and networking opportunities available to members.

Local Groups who bring in the most new PASS members over the three month period, will be awarded VISA gift cards, in the following eight categories:

• USA/Canada – Small Group, Large Group

• EMEA – Small Group, Large Group

• LATAM – Small Group, Large Group

• APAC – Small Group, Large Group

Note: Small Groups = 250 members or less, Large Groups = 250+ Members
