Fields spent 27 years working at the Youngsville Fire Department.
A procession was held with some streets blocked off in honor of the man who served and protected the community for almost 30 years.
"It's hard to imagine how things are going to run here without Jeff," Asst. Fire Chief David Williams said.
Following the procession, a service was held where family, friends, and emergency responders from the area came together.
"He was just one of those guys who would take his shirt off his back and give it to you if you were ever in need," Williams said.
Fields died on December 25 after his family found him unresponsive.
He had a heart attack earlier in December and was released from the hospital.
"It was a shock to us that we lost Chief Fields. Because of his activity, service, and dedication it's a big, big hole not only in our hearts but the fire department itself," Williams said.
Fields started volunteering with the department in 1984 and worked his way up the rank to assistant fire chief.
He leaves behind two teenage children. One of them a 19-year-old daughter who followed in Fields' footsteps and is also a volunteer with the department.
"Just no words to describe how I feel for his family and our brotherhood of firemen here in Youngsville," Williams said.
However, the overwhelming support by the community is helping those hurt to heal.
"[Support] has just been tremendous. You can tell by that outpouring of care and love that they had for Jeff that he had an impact on this community," Williams said.
