Dr. Roger Seheult Dr. Roger Seheult is the co-creator of MedCram Videos. In the early days of the COVID-19 pandemic, MedCram emerged as a beacon of insight, providing continuing coverage and perspectives in an environment almost defined by information scarcity. What particularly excited me about the unique opportunity of this interview is that apart from Dr. Seheult being a unique voice of public scholarship during the early days of the pandemic, he's also a quadruple board-certified pulmonologist with deep experience working on the frontline of the COVID-19 pandemic.
