The minds behind
the method.

Dr. Vicente Gracias is a nationally recognized physician executive, surgeon, and healthcare innovator who has spent his career improving how people and systems perform under pressure.

As Senior Vice Chancellor for Clinical Affairs at Rutgers University and Vice President for Health Affairs and Chief Academic Officer for RWJBarnabas Health, he leads initiatives that impact millions of patients while advancing clinical excellence, leadership development, and healthcare transformation.

A Professor of Surgery and former University of Pennsylvania faculty member, Dr. Gracias brings a rare combination of frontline clinical expertise, academic rigor, and large-scale systems leadership. His work has focused on improving performance, from health systems and clinical outcomes to the human factors that influence decision-making, resilience, and sustained excellence.

At iCalibrate, he helps bridge cutting-edge neuroscience, performance science, and real-world application to create practical pathways for lasting change.

Dr. Grant is one of the most distinguished neurosurgeons in the world. As the Allan H. Friedman Distinguished Professor of Neurosurgery at Duke, he chairs one of the leading neurosurgery departments in the country, with a clinical focus on brain tumors, epilepsy, and concussion.

He has been named a Director of the American Board of Neurological Surgery, the highest distinction available in the field, and previously served as Chief of Pediatric Neurosurgery and Vice Chair at Stanford Medicine, one of the most prestigious positions in academic neurosurgery.

Dr. Grant is the author of over 365 peer-reviewed journal articles and remains an active NIH Principal Investigator in focused ultrasound and brain tumor immunotherapy. He served as Chief of Neurosurgery at Wilford Hall Air Force Medical Center and was deployed as Chief of Neurosurgery in support of Operation Iraqi Freedom.

Dr. Fisher serves as Editor-in-Chief of The Journal of Pediatrics, the primary authority for pediatric clinical science worldwide. In this role, he shapes the global standard of what constitutes rigorous, publishable pediatric medicine.

At Stanford Medicine, he holds the Beirne Family Professorship in Pediatric Neuro-Oncology, has served as Interim Chair of the Department of Neurology, and led the Division of Child Neurology for 15 years, one of the longest tenures in the department's history.

Dr. Fisher is the author of over 300 scholarly publications, with a focus on neuro-oncology and the late effects of childhood brain tumors. He currently serves as lead investigator on cutting-edge CAR T-cell therapy trials for relapsed medulloblastoma, one of the most ambitious frontiers in pediatric cancer research.

Dr. Scheinker occupies a unique position in the iCalibrate board: he is the architect of how clinical data becomes system-level insight. With a PhD in Theoretical Mathematics from UCSD and a Joint Research Fellowship at The MIT Sloan School of Management, his work sits at the precise intersection of mathematical rigor and real-world healthcare impact.

As Executive Director of Systems Design at Stanford Lucile Packard Children's Hospital and founder of SURF, the Stanford University Research Factory for Health Care, he has built and deployed AI and mathematical modeling systems that have fundamentally changed how chronic diseases are managed using high-frequency data.

His research spans 120+ publications, with landmark projects including the "4T Study" and the "Timely Interventions for Diabetes Excellence" (TIDE) platform, tools that have been adopted at scale across major health systems. His presence on the iCalibrate board ensures that the method's outcomes are not anecdotal, they are measurable, mathematically structured, and scalable.

Allison brings 20 years of experience transforming operations through business development, strategy, program management, and product design, having worked with CB Richard Ellis (CBRE), Trinitas Farming, and Pomona Farming. A key architect of iCalibrate, she holds an undergraduate degree from Claremont McKenna College and a master's degree from Stanford University. She resides in Menlo Park, CA, with her husband, two children, and two dogs, and enjoys dancing, family movie nights, economics podcasts, and football.

Dina Brewer brings more than 30 years of experience advising leaders and building organizations across sectors. Trained at Princeton University and Harvard Law School, Dina spent the first part of her career in global finance and strategy — helping emerging companies grow with clarity, integrity, and purpose.

After decades in high-stakes corporate environments, Dina became passionate about what sustains performance over the long term — how purpose, resilience, and human connection drive not only success but well-being. Today, she applies that same strategic acumen to support mission-driven ventures like iCalibrate, helping bridge business, science, and the human spirit.

Beyond her professional work, Dina is deeply involved in community leadership and education, serving on numerous Princeton-based boards and mentoring the next generation of conscious leaders. She lives in Princeton, New Jersey with her husband, three daughters, and two dogs — and is most at home outdoors, exploring national parks or running new trails.
