There are different SMA groups and foundations that target specific kids or the cause in general. I strongly suggest making donations to the Gwendolyn Strong Foundation, whose famous motto is NEVER GIVE UP.
Gwendolyn has a very special place in our hearts, and although she passed away, her memory is very much alive through her foundation. They help through many means, so please go visit http://thegsf.org/.
We also know kids in Puerto Rico that can use your help. If you are compelled to assist, drop us a note and we will put you in contact with the right family.
