Cheyenne DeVelasco MIB Agents Fund


Cheyenne DeVelasco passed from this life on Sunday, August 20th, 2017.  She will surely rest peacefully knowing she was loved deeply, she loved greatly and gave of herself wholeheartedly until the very end of her life.  

She lived the life of a true superhero – having faced great adversity, she used her considerable powers for good, for all.  

Weeks before Chey passed away, when breathing was difficult, and she had every right to not engage with others, she courageously shared her story with MIB Agents and their video production team.  Her story, strength, faith and love will be shared with the world.    More than a Warrior, Chey showed us all how to battle adversity with courage, hope and faith.

Chey was an important part of MIB Agents from the start.  She was a sustaining donor, sending a donation every month to help other kids and young adults suffering from her same disease, osteosarcoma.  Her heartfelt desire was to Make It Better so that no other child should have to suffer as she did.

Cheyenne’s asked that in lieu of flowers, donations be made in her name to Make It Better for others still fighting, and yet to fight osteosarcoma.
