    The CNS Foundation is pleased to announce Chrystal Calderon, BMedSci (Hons), MBBS (Hons), MRCS, of Trinidad and Tobago, is the winner of the CNS Foundation Massachusetts General Hospital (MGH) 2022 International Observership for Neurosurgery.

Dr. Calderon will also participate in weekly coursework at the Program in Global Surgery and Social Change at Harvard Medical School.

     “This robust combination of education and in-person learning is precisely what we envisioned when the CNS Foundation launched the International Portfolio,” said CNS Foundation Co-chair, Martina Stippler, MD. “The mutual exchange of information extends beyond Dr. Calderon’s education in Boston. She will be also able to share her own unique knowledge of practicing in the Caribbean with her classmates during her time at the Global Surgery Program.”

    “The CNS Foundation relies on so many world-class partners to make this phenomenal offering possible. Our generous CNS Foundation donors and the leadership of Drs. Brian Nahed and Myron Rolle brought this program to life. Thank you to Harvard’s Program in Global Surgery and Social Change alongside the Massachusetts General Hospital for opening your doors and providing a truly meaningful experience for global neurosurgeons,” said CNS Foundation Co-chair, Alexander Khalessi, MD, MBA.

     Dr. Calderon is currently a faculty member of the University of the West Indies at St. Augustine, Trinidad and Tobago. Her current special interests are in Neurooncology and Pediatric Neurosurgery. With respect to the latter, she is focused on furthering her research on myelomeningoceles and hydrocephalus incidences at her tertiary institution.

     The CNS Foundation offers an International Portfolio of opportunities for those who wish to advance neurosurgical programs globally. To learn more please visit
