Join the IDF Sustainer's Club

Your monthly donation demonstrates your commitment to people with PI.

Benefits of monthly giving

Thank you for considering joining the IDF Sustainers Club, our most committed group of primary immunodeficiency (PI) supporters. Your monthly gift will make a tremendous difference in the lives of those affected by PI.

Tailored to you

You can give in a sustainable way by donating an amount that is manageable for your budget. We appreciate gifts at all levels, whether they are big or small.


Your donation occurs automatically each month, so you don't have to worry about remembering to make a donation. You can change the amount or cancel anytime.


Monthly giving means lower administrative costs, so more of your money goes to where it's needed most: educating and advocating for the PI community.

Long-term impact

Your monthly donation allows us to have a long-term, planned approach towards fulfilling our mission and making a difference every day.


You will join a club of individuals with the goal of improving the lives of those with PI. Additional benefits include recognition in IDF's Annual Report, CEO quarterly updates and special invitations to events.

All the stripes on a zebra add up, and so do your donations. Your monthly donation might not seem like much, but when you combine it with all members of the IDF Sustainers Club, it will make a huge difference.
