Abby Brody
New York, NY
Abby is a lifetime educator with over 15 years of experience in the classroom and 12 years in administration. With MYX, she is leading the charge to present a new approach to higher education that meets the needs of the 21st century by creating experiences for young adults to find their life purpose while also gaining essential skills for life success.
It all started when she founded Mind the Gap, an organization devoted to studying why higher education was failing its students and designing solutions. In her research, Abby began to see that students are not being served by the traditional college track, which often leaves them shackled in debt and without life skills to succeed in the workforce. Coupled with the fact that that the value of higher education with respect to life success has less to do with credits and more to do with experience, the solution became clear.
Abby assembled a team of fellow educators with deep expertise in traditional higher ed, experiential learning, place-based learning and more, then added a dose of real life with coaching and culture experts who could help serve the needs of the whole student as they set out to create their future.
Prior to founding MYX, Abby was a founding member of Avenues: The World School where she held multiple leadership positions, helping develop the first interconnected global independent school.
Abby earned her B.A. at Duke University and her M.S. in special education from Bank Street College.

Emily Rottier Goebel
Alexandria, VA

Emily is an attorney whose practice has focused on securities litigation, white collar defense and other complex commercial litigation. A graduate of the University of Virginia School of Law, Emily began her career at Mayer Brown LLP in New York and most recently worked as Associate General Counsel in the General Counsel’s office of the Financial Industry Regulatory Authority (FINRA), ushering emergency regulatory relief for the securities industry during the COVID-19 crisis.


Following her son James’s diagnosis of stage 4 neuroblastoma in December 2020, Emily learned that pediatric cancers are underfunded at the federal level and, as a result, progress for cancers like neuroblastoma is highly reliant on private funding through organizations like Band of Parents (BOP). The critical nature of BOP’s private funding efforts came to light when James was deemed to have widespread chemo-resistant disease and the next line of defense, and what ultimately cleared his disease, was Hu3F8 – the immunotherapy that drove Band of Parents to form. Given the importance of BOP’s work in saving James’s life, Emily and her family are fully committed to fundraising for BOP and working to change the future for neuroblastoma warriors.                                                   


Emily, along with a community of incredible supporters and enthusiastic team captains, has also led a 5-city top national team for Cycle for Survival since 2021, Team SuperheroJames. Her team has raised over $350k for rare cancer research and neuroblastoma, with all direct donations going to neuroblastoma research at Memorial Sloan Kettering in New York, including the Band of Parents funded neuroblastoma vaccine trial. In 2022 and 2023, Team SuperheroJames was the no.1 and no. 2 team in Washington, D.C., and her team is looking forward to tackling neuroblastoma and rare cancer on the bikes again in 2024.

Pediatric Hematology/Oncology


Dr. Nai-Kong Cheung is a pediatric oncologist and cancer researcher at Memorial Sloan Kettering Cancer Center (MSKCC) in New York, specializing in immunologic approaches for the diagnosis and treatment of pediatric cancers.  At Harvard Medical School, he studied suppressor T cells and B cell tolerance under the mentorship of Dr. Baruj Benacerraf, the 1980 Nobel laureate in Medicine.  Upon completing his pediatric training in Pediatrics and Pediatric Hematology/Oncology at Stanford, he has devoted his entire career to translational science, with a clinical focus on neuroblastoma, and a research focus on antibody-based therapies.


Dr. Cheung built the neuroblastoma program at MSKCC from the ground up in 1987, exploring dose intensity and consolidation with antibody-based immunotherapy, engaging a multidisciplinary disease management team, enabling MSKCC to be a major referral center for neuroblastoma, registering more than 100 new patients a year for over 25 years.  Over three decades at MSKCC, he has developed from bench to the bedside several monoclonal antibodies, including 3F8 and its humanized form (hu3F8, naxitamab) specific for ganglioside GD2, and 8H9 (omburtamab) specific for B7-H3.  For high-risk metastatic neuroblastoma, patient survival has steadily improved as 3F8 was successfully applied to eradicate bone marrow metastases, and 8H9 to salvage CNS relapse.  Naxitamab received FDA breakthrough therapy designation (BTD) in 2018 and FDA approval in 2020, and omburtamab received BTD in 2017.  This academic translational paradigm from discovery to GMP manufacture, IND application to early phase trials before transition to pharmaceutical sponsor has yielded several new leads for unmet needs in cancer.


More recently, Dr. Cheung has devoted full time to laboratory research developing new antibody platforms to engage T cells and to improve precision in the delivery of beta particle and alpha particle therapies.  Ganglioside tumor vaccines, beta glucan adjuvant, and novel IL15 cytokine complexes are areas of active clinical investigation.  He has pioneered immunocytology and molecular markers to measure minimal residual disease, as well as biomarkers of tumor response, while collecting and managing a rich human tumor and tissue archive to facilitate studies of treatment-related leukemia, neuroblastoma clonal evolution, and immune profiling.  He has published >370 peer reviewed articles (https://shorturl.at/mFKT5) plus >70 book chapters or reviews, and he was named as an inventor on 50 patent families filed by MSKCC.


Dr. Cheung is actively involved in teaching and mentorship of students, residents and fellows in oncology.  He participates in the efforts of professional organizations, including the Children’s Oncology Group, American Association for Cancer Research, the American Society of Clinical Oncology, and the Society for Immunotherapy of Cancer.  Through the NK and Irene Cheung Family Charitable Fund, he is active in philanthropic support of education, training, and patient welfare, while being a strong advocate for pediatric cancer care in the US.

Radiation Oncology


Since 1998, I have been the Director of Pediatric Radiation Oncology on the MSK Kids team who cares for children and young adults with cancer.


I have extensive experience treating rare diseases in children, including neuroblastoma. Radiation therapy is an extremely powerful tool for these tumors, but young patients are especially sensitive to long-term side effects. I therefore approach each patient as a unique individual, carefully designing a highly customized radiation therapy plan to maximize the benefits of treatment while minimizing side effects. I am a leader in the use of targeted approaches such as proton therapy, intensity-modulated radiation therapy, image-guided radiation therapy, and intra-operative radiation therapy for pediatric cancers.


We are very mindful of patients’ long-term quality of life and seek to maintain the highest possible survival rates while minimizing the risk of potential long-term treatment complications. I am involved with research on the late effects of radiation therapy through my collaboration with the Childhood Cancer Survivor Study. I currently have an open study at MSK testing reduced dose radiotherapy for the primary site in high-risk neuroblastoma.


I find it very rewarding to work with a team that couples extraordinary experience with compassion to care for patients with cancer. I am optimistic that our ongoing research will lead to higher cure rates as well as improved long-term quality of life for our patients.

Amit Sanghvi – Warrior of the Band
Ann Arbor, MI

Amit is a Warrior of the Band! He was diagnosed with stage IV Neuroblastoma when he was almost 3 and it nearly took his life. His odds were not great, but he is one of those fortunate enough to say they’ve beat this terrible pediatric cancer. After brain surgery to remove the tumor around his optic nerves, chemo, radiation and the super power of 3F8, Amit successfully defeated Neuroblastoma.


Amit has been in remission for over 18 years, but his fight with Neuroblastoma left him legally blind. Even so, he refuses to let that stop him from living life to the fullest.


As a high school Senior in 2016, Amit won the Student of the Year for Individuals with Disabilities Award. He is an avid baseball fan and has been Home Run Champion at the Miracle League of Arizona multiple times. Amit also has skills on the court: in 2017, he led his Arizona Special Olympics basketball team to a 3rd place finish in the district tournament (winning the Bobcat of the Year “best player” award) and this year, in 2020, he helped his Special Olympics basketball team in Michigan qualify for the State Championship Tournament.


Amit is currently a 3rd year Pre-Business major at the University of Michigan—Dearborn.


Neuroblastoma is a devastating disease and Amit wants to be on the front line with the army that defeats it. It caused his family a lot of heartache and suffering and Amit is determined to do everything he can to prevent any other family from going through the same. Along with Band of Parents, Amit is committed to winning our war of hope to bring an end to Neuroblastoma.
