We are always looking for new members to join our community of help and support. If you have a child with mastocytosis, or want to be a supporter of Mastokids, please follow the steps below. Members have access to the private Facebook group.

1) Fill out our membership application.

2) Submit the $12 membership dues by PayPal to payments@mastokids.org. Please choose friends and family so that mastokids does not have to pay a fee for the transaction. (If you prefer, you may send a check to the address at the bottom of this page.)
