Medical Advisory Board

Scientific Leadership And Results

The Lisa Colagrossi Foundation Scientific and Medical Advisory Board (SMAB) is composed of leading neurosurgeons and healthcare professionals from institutions across the United States who specialize in Brain Aneurysms. The SMAB provides scientific and clinical expertise to guide us in planning and implementing our research initiatives and our information and education services for patients, their families and caregivers, and healthcare professionals.

All SMAB members contribute their expertise on a voluntary basis with no conflict of interest between their professional work and the volunteer work they do for The Lisa Colagrossi Foundation.
