Histiocytosis Association Support Group Sessions

For those navigating histiocytosis, we invite you to choose the support group that best fits your needs — whether you are a patient, caregiver, grieving a loved one, or seeking connection.

Our Peer-to-Peer Support Groups provide safe, welcoming spaces to share experiences, feel understood, and find community and hope. Not sure which group is right for you? Contact our Program and Outreach Coordinator, Melinda Atnip, at matnip@histio.org for guidance.

We strongly encourage all ideas shared by your peers to be discussed with your physician and/or care team. The Histiocytosis Association designed these sessions to be open, safe, and respectful environments for all who participate. We encourage you to review our Virtual Event Participant Guidelines before joining a call. If you have any questions, contact us at info@histio.org.
