At the heart of our mission is a commitment to advancing research and advocating for the needs of both patients and healthcare providers. To ensure we remain at the cutting edge of clinical excellence and ethical research, we have established a Scientific and Medical Advisory Board (SMAB) built on a foundation of merit, expertise, and shared purpose.


A Multidisciplinary Volunteer Coalition


Our board is comprised of dedicated volunteers from a diverse range of practices, research institutes, and medical specialties. We believe that breakthroughs happen when different perspectives converge. Because our primary goal is the furtherance of our mission, we prioritize individual expertise and commitment above all else:


  • Diverse Representation: Members are selected based on their unique contributions to their fields, regardless of their institutional home.
  • Institutional Independence: To gather the best minds, we may welcome multiple experts from the same institution. We view these overlaps as a testament to the excellence of those specific centers, rather than a limitation on our board's diversity.
  • A Focus on Integrity: Each member is chosen for their personal integrity, ethical standing, and proven track record in patient advocacy and scientific rigor.


Mission Over Politics


In an era of complex social and external dynamics, our board remains steadfast in its focus. The selection process and the board’s subsequent actions are governed strictly by scientific merit and medical ethics, not by social or external politics.

By removing political and institutional barriers, we create a space where the sole focus is the advancement of research and the empowerment of the medical community. This allows us to provide unbiased, evidence-based guidance that truly serves the interests of the patients and doctors we represent.
