INDIANAPOLIS (WISH) — Eighteen EMTs and five paramedics were sworn in Tuesday night to Indianapolis Emergency Medical Services.

The new recruits had to train four weeks. The training allows Indianapolis EMS recruits to become familiar with Marion County public safety.

Tuesday’s group of graduates is the second-largest single recruit class for Indianapolis EMS. They will join more than 300 colleagues out on the roads.

The graduates were pinned by friends, family and loved ones at the ceremony at an Indianapolis EMS facility on the northwest side of Indianapolis.

Dr. Dan O’Donnell, chief of Indianapolis EMS, said, “Their journey is beginning. They are about to start getting heavily involved in their field training officer program and then moving on into the streets and start providing care. So, I think it’s combined of nerves and excitement at the same time.”

Indianapolis EMS responds to more than 100,000 911 calls each year, making it the largest provider of emergency prehospital care in the state.
