"Hi, my name is Ernesto Cardenas. I'm an OB/GYN and captain in the U.S. Army. Right now, I'm stationed at Fort Sam Houston, in San Antonio, Texas, working out of the Brooke Army Medical Center.
I was born in Colombia and came here at age five. Growing up, I wanted to serve the country that had given me and my family so much. Medical school was a logical choice. The amazing thing is that I was actually paid to go to school and learn to do more.
The rewards of service – like being deployed to my native Columbia to help those in need, and when Katrina and Rita hit, delivering babies of displaced people – getting them car seats and housing – it's just indescribable.
For recreation, well, my dad and I were car mechanics and I still like to rebuild engines and race motorcycles."
