Jonny Kim

Jonathan Yong Kim was born on 5 February 1984 in Los Angeles, California.^[5] His parents emigrated from South Korea to the United States in the early 1980s,^[6] and his father had scarcely completed a high-school education. The family opened a liquor store in South Los Angeles, and his mother worked as a substitute elementary school teacher while raising Kim and his younger brother.^[7] In a 2018 interview with Annals of Emergency Medicine, Kim described himself as "the epitome of that quiet kid who just lacked complete self-confidence."^[8] In 2020, The Chosun Ilbo reported that the adolescent Kim had been the victim of domestic violence at the hands of his father; in February 2002, after threatening his family with a gun, Kim's father was shot to death in his attic by police.^[9]

Kim graduated from Santa Monica High School in 2002 where he received high grades in his classes, including several Advanced Placements, while participating in swimming and water polo.^[10][7] While a member of the Navy, Kim received a Bachelor of Arts, summa cum laude, in mathematics from the University of San Diego in 2012, and a Doctor of Medicine from Harvard Medical School in 2016. Kim was a Pat Tillman Foundation "Tillman Scholar" selectee. In 2017, Kim completed his medical internship in emergency medicine at Massachusetts General Hospital and Brigham and Women's Hospital.^[10]

Special warfare

Kim learned about and decided to become a Navy SEAL at age 16, investing his remaining high-school years physically conditioning himself for the rigors of Special Warfare training. Of this decision, Kim said, "Going into the Navy was the best decision I ever made in my life because it completely transformed that scared boy who didn't have any dreams to someone who started to believe in himself."^[8]

After enlisting with the United States Navy in 2002 as a seaman recruit, Kim graduated BUD/S class 247 and was assigned to SEAL Team 3 with the rating Special Warfare Operator. He deployed twice to the Middle East and participated in over 100 combat missions as a combat medic, sniper, navigator, and point man.^[10] During his tenure with the SEALs, Kim served with PO2s Marc Alan Lee, Michael A. Monsoor, Jocko Willink, and Chris Kyle.^[11][12]

In addition to completing the Naval Flight Surgeon Course, Kim received the rare Aeromedical Dual Designator (AMDD).

Kim is a recipient of a Silver Star, Bronze Star Medal (with Combat "V"), the Navy and Marine Corps Commendation Medal (with Combat "V"), and Combat Action Ribbon.^[11] According to Jocko Willink, Kim's Silver Star was awarded for rescuing multiple wounded Iraqi soldiers in the face of enemy fire.^[12] As of November 2025^[update], Kim is a member of the Navy Reserve with rank of lieutenant commander.^[2]

As a Navy SEAL corpsman during the Iraq war he was inspired to pursue medicine.^[15]

Following his graduation from Harvard with a M.D. in 2016, he began a residency in emergency medicine through the Harvard Affiliated Emergency Medicine Residency (HAEMR) program at the Massachusetts General Hospital and Brigham and Woman’s Hospital and commissioned into the Navy Medical Corps.^[16]

During his tenure at Harvard, he would met Scott E. Parazynski, a physician and former NASA astronaut, who inspired him to apply for Astronaut Candidacy.^[17] Just a year into his residency,^[18] on 7 June 2017,^[19] Kim was one of twelve candidates chosen from a pool of over 18,300 applicants to join NASA Astronaut Group 22.^[20] Prompting him to leave clinical training, he reported for duty on 21 August 2017,^[17] and graduated from training on 10 January 2020.^[21]

He would later complete a year long postgraduate internship (PGY-1) and attend the Naval Aerospace Medical Institute (NAMI), becoming a naval flight surgeon.
