President Donald Trump underwent his first medical exam while in office Friday at Bethesda, Md.-based Walter Reed National Military Medical Center. The exam was conducted by Rear Adm. Ronny Jackson, MD, who has served as the official physician to the president since 2013.
Here are five things to know about Dr. Jackson.
1. Dr. Jackson, a native of Levelland, Texas, received his undergraduate degree in marine biology from College Station-based Texas A&M University. He received his medical degree in 1995 from the Galveston-based University of Texas Medical Branch, according to his biography on the website for the U.S. Navy.
2. He began his active duty naval service in 1995 at the Portsmouth (Va.) Naval Medical Center, and returned to PNMC in 2001 to begin his residency in emergency medicine.
3. Dr. Jackson was selected to serve as a White House physician in 2006, and has provided care to White House officials during the past three administrations.
