Rachel Krieger's son Oliver was diagnosed with the Pediatric Brain cancer Atypical Teratoid Rhabdoid Tumor when he was 9 months old in April of 2019. Oliver is now approaching his 6th birthday and has been considered stable since 2022.

Rachel Krieger is a Primary Nurse Practitioner and when her son Oliver presented troubling physical symptoms when he was 9 months old, Rachel took him to the pediatric emergency room at New York University where an MRI revealed a large tumor on his Cerebellum in April of 2019. This tumor turned out to be the Pediatric Brain cancer known as Atypical Teratoid Rhabdoid Tumor or ATRT. Oliver has gone through some very toxic and difficult treatments including a full brain and spine radiation procedure. Oliver was considered stable in 2022 and is still considered stable as he approaches his 6th birthday.  Rachel will talk about her son's fight and about the Non-Profit Ollie's Orchestra that she and her husband Max started to help pediatric cancer patients.
