Cross-Continental Collaboration

World-Class Pediatric Neurovascular Care

BLT is a global alliance of leading clinicians and researchers in Boston, London, and Toronto—dedicated to advancing diagnostics, treatment, and research in complex pediatric neurovascular conditions.

Why BLT Was Created

BLT was founded by a group of pediatric specialists who believed collaboration could save lives. Faced with complex neurovascular cases and fragmented research, they imagined a space where knowledge, not geography, would define the quality of care. Today, BLT brings together some of the world’s most respected institutions to solve the unsolvable—together.
