The department said the firefighter, who was not named, was recuperating at Kendall Regional Medical Center and "feeling isolated from the rest of the world."
Video released by Miami-Dade Fire Rescue shows a fire truck from Station 36 arriving outside the hospital as firefighters begin to set up to send their greetings.
"There they are, all this for me," the firefighter can be heard saying in the video, in-between heavy breaths.
After gearing up and equipped with "Get Well Soon" cards, firefighters then approached the fourth-floor hospital window on the fire truck's ladder.
One firefighter held up a sign that read: "Your New Firehouse."
The firefighter on the ladder and all on the ground wished their colleague a speedy recovery on behalf of the entire department.
“This is love. This is the only kind of love you can get from the brother and sisterhood at the firehouse," the MDFR firefighter can be heard saying in the video. "There is just no other way to explain how this makes me feel."
