Chelsea Johnson, MD
Chelsea Johnson was born at Bethesda Naval Hospital while her dad was stationed in Maryland as a navy pilot before moving to Keller, TX where she began springboard and platform diving. She was fortunate enough to represent the USA at Junior World Championships and continue diving as a Division I athlete for Purdue University.

The two have a cat, Rafiki (Swahili for friend––named after experiencing the beautiful language and people of Tanzania). Outside of medicine, Chelsea and her husband enjoy being active and outdoors. They support division rivals, Houston Texans and Indianapolis Colts; therefore, they expect to have marital hardship twice a year.
