Patient story

Marcus's Story

"A Children's National ambulance picked up my son. Of course he thoroughly enjoyed the ambulance ride because he got to watch a movie along the way - not to mention the ambulance personnel were sensitive and nice, and kept him informed of their every move."

Maggie's Story

"This is a difficult journey. I had pictured a million scenarios, but luckily for Maggie, it worked out wonderfully and now we have our baby girl back and we can concentrate on her and our family and keeping her healthy."
