Today the company responds to emergency and non-emergency calls in Louisiana;[1] Southeast, Central, and North Texas;[2] Jackson County, Mississippi;[3] Nashville and Memphis, Tennessee.

Acadian was founded by Roland Dugas, Richard Zuschlag, and Rolland Buckner in response to funeral homes ceasing to provide ambulance services because of new, financially burdensome federal guidelines.

In 1976, Acadian expanded their EMT training, formalizing it and fully certifying employees through the National Registry of Emergency Medical Technicians and the state of Louisiana.

Today, Acadian has more than 4,000 employees across six divisions— ranging from Nationally Registered Emergency Medical Technicians and pilots to health, safety, and security professional and support staff.

Air Med Services Surrounding parishes became interested in having Acadian Ambulance's pre-hospital emergency care and soon invitations to serve came in from other areas.

Louisiana's diverse geography of rich swamps and marshlands, and extensive rural areas, made navigation in a ground ambulance an often difficult task.

Safety Management Systems At its inception, Air Med was the first aero-medical provider in the Gulf of Mexico with helicopters equipped like a hospital emergency room and flight paramedics.

With this in mind, the National EMS Academy was launched in 2003 through collaboration with South Louisiana Community College, so Acadian could educate its own medics.

[12] On March 26, 1998, US Attorney Mike Skinner announced that Acadian Ambulance had agreed to pay the federal government $1.9 million to settle a lawsuit that charged the Lafayette company with overbilling the Medicare and Medicaid programs from 1990 to 1994 by offering a greater discount to members than allowed by law.

Acadian won summary judgement in the trial court but the Louisiana Court of Appeals, Third Circuit, reversed the summary judgment on May 31, 2006, saying, "[the] increasing complaints after the patient reported a rough transfer from bed to stretcher at Women's, this evidence is sufficient to raise a material issue of fact as to how, when, and where the fracture occurred, as well as to the possible fault of Women's and Acadian Ambulance.

"[15] On December 27, 2010, while transporting a pregnant patient, an Acadian Ambulance unit collided into the rear of a sugar cane truck near Brusly, Louisiana.

Prior to landfall, they were notified of multiple requests to evacuate hospitals as well as home-bound patients, including Dorothy Hingle, 83, and her son, Russell Embry, 54, from their home due to the pending hurricane.

They contacted Ms. Hingle as well also others on the list on August 26, 2005, and confirmed they still needed to be evacuated as they had arrived at other homes and the individuals had already left by other means.

[23] On December 12, 2012, Acadian Ambulance was ordered to pay $17 million in a class action lawsuit against them by 12th Judicial District Judge Mark Jeansonne.

[24][25][26] Acadian Ambulance appealed the trial court’s ruling and the plaintiffs agreed to settle the class action lawsuit for less than $5 million in June, 2014.
