On #WorldMentalHealthDay, we affirm our commitment to breaking the stigma around mental health and supporting the well-being of our colleagues and the patients we serve.

Earlier this month, Syndaxers came together for our Fall Commercial Meeting in Nashville, which centered on sharing knowledge, celebrating our achievements and strengthening our commitment to the patients we serve. The numerous panels and workshops featuring Syndax leadership and cross-functional colleagues reinforced our mission to reimagine cancer care, and the excitement for what we are delivering on was palpable. We also learned about the promise that inspired Pinky Swear Foundation – one child’s wish to help other families facing childhood cancer, and a father who carried that wish forward. During the meeting, Syndax colleagues wrote letters of hope, strength and support to families navigating cancer through Pinky Swear’s Orange Envelope program. Thank you to the presenters, colleagues and special guests who joined us for this incredible event! #WeFlyHigherTogether

This September, during #ChildhoodCancerAwarenessMonth, we pause to honor lives lost and stand alongside young heroes, resilient families and dedicated care teams in the fight against pediatric cancer. Syndax is proud to continue our support of pediatric patients by partnering with the Oliver Patch Project to sponsor a special goose patch. Designed by Olivia, an Oliver Patch Project Warrior, this patch was created to bring hope, connection, and a sense of community to children facing cancer and other health challenges. Our Syndaxers had a chance to show the patches off before distribution to brave young patients around the world. #WeFlyHigherTogether #PassionforPatients
