Dr. Calvin D. Sun is an emergency physician and clinical assistant professor in emergency medicine. When the COVID-19 pandemic hit New York City, Dr. Sun worked at emergency rooms all over the city and soon gained a substantial online following from sharing his insider experiences and advice.

Dr. Sun has been a frequent guest on national and international new programs to help inform others of the pandemic situation in New York City. He brings medical knowledge and empathy to the story of COVID-19 and is no stranger to grief himself, having lost his father when he was just a teenager, and his grandfather to COVID-19.

Over the past ten years, Dr. Sun has traveled to over 190 countries, while also completing medical school and going through medical residency. With his organization, the Monsoon Diaries, he has led other everyday travelers around the world on memorable adventures.
