Philip Rotner is the chief investment officer at Boston Children's Hospital, where he manages the hospital's endowment, pension, and short-term investment assets. In this interview, he explains why Boston Children's Hospital continues to be ranked as the number one pediatric hospital in the world, how Boston Children's built its proprietary investment model to support its mission of treating sick children, and how health system's don't ordinarily plan to sustain 12 months of losses caused by a pandemic. Although, Phil adds that investment markets have done just fine despite a challenging 12-15 months.
