The LifeNet Story
30 years ago, two Texarkana hospitals, CHRISTUS St. Michael and Wadley Regional Medical center recognized the strength in working together to serve the out-of-hospital patient care needs of the community. In 1993, the hospitals merged their ground and air ambulance programs into one company and called the new business LifeNet, Inc.
Today, nearly 350,000 people depend on LifeNet for ground ambulance service across Northeast Texas, Southwest Arkansas, and portions of Oklahoma. LifeNet now operates as an independent, non-profit company incorporated in the state of Arkansas and is overseen by a 15-member board of directors.
Started as Air Life by CHRISTUS St. Michael hospital in 1983, the LifeNet Air medical program is the oldest operating helicopter EMS program in the state of Arkansas. Through a partnership with Air Methods, LifeNet has helicopters at both the Texarkana, Hot Springs and Daingerfield Texas. The three bases have flown more than 15,000 patients and provide service throughout three states. LifeNet also operates a fixed wing ambulance out of Texarkana.
While LifeNet is known for putting the patient first and providing quality EMS service, there’s more.
LifeNet is also committed to improving education in the communities we serve. Through its generous tuition reimbursement program, LifeNet has helped EMTs become paramedics, paramedics become nurses, and other staff members to become teachers, business professionals, and even attorneys.
Recognizing it is important for the citizens who witness an emergency happen to be trained in how to respond until help arrives, LifeNet also provides free Stroke Awareness Education Programs, Stop the Bleed Training Classes, and 9-1-1 training for all age groups. LifeNet also works to improve sudden cardiac arrest survival rates by offering free Bystander CPR and AED Use classes and an AED Matching Grant program for non-profits.
2023 marked 30 years of patient care, employee enrichment and lives that have been saved. We are celebrating the employees that have been with LifeNet since the hospital days, and the new employees and children that now work on our trucks. LifeNet is celebrating the past, but looking towards the future as we continue to better ourselves as a company, an EMS provider, but ultimately as healthcare providers, serving our communities each day.
CAAS-Accredited
LifeNet is in the one percent of ground ambulance services nationally to be CASS accredited. In 2019, LifeNet earned its accreditation from the Commission on Accreditation of Ambulance Services (CAAS) for the fifth time since first becoming accredited in 2000. To receive accreditation renewal, LifeNet had to meet over 100 standards set by CAAS covering structure, interagency relations, management, finance, community relations and public affairs, human resources, clinical standards, safety and risk management, equipment and facilities, and communication centers.
After reviewing a comprehensive application that covered LifeNet’s policies, procedures, and protocols, CAAS inspectors visited LifeNet’s three divisions in 2021 and conducted a detailed two-day inspection. The visit included checking facilities, reviewing procedures and protocols, and interviewing personnel. This was the seventh time since 2000 that inspectors have done in-depth, on-site reviews of LifeNet Inc.. In 2024, LifeNet’s 8th review took place awarding another 3 year accreditation. The next review will take place in 2027.
While accreditation is not required to run a ground ambulance service, LifeNet is committed to excellence and putting the patient first. By undergoing recertification every three years, LifeNet ensures the company is providing the best EMS service possible in each service area.

Joshua Norred
Base Manager, Texarkana
Born and raised in north central Louisiana, I graduated from Quitman High School. I attended Louisiana Tech for a short stint before deciding I was not ready for school and chose to pursue welding, which I had done for most of my life.
After deciding that welding was not the career I wanted to continue, I attended the University of Louisiana at Monroe with the initial thought of studying kinesiology and hopes of going to physical therapy school afterward. When I moved to Monroe, I was able to get a job as an ER tech at St. Francis Medical Center in Monroe, Louisiana, where I worked from 2013 to 2015. This was my first introduction to what could be done within nursing. With that experience, I quickly changed my major to nursing with the hope of becoming an ER nurse.
After multiple failed attempts at being accepted into nursing school, I decided to get a degree in Occupational Safety and Health, which I completed in 2017. With that degree, I was able to complete an internship and then work as a safety engineer for WestRock in Jonesboro, LA for 2 years.
In 2019, I decided my heart was still set on becoming a nurse, so I applied to the Louisiana Tech nursing program, where I was accepted and completed my associate degree in February 2022. While working on my nursing degree, I also returned to St. Francis Medical Center and worked as an ER tech for a second time from 2019 to 2022.
After graduation, my first nursing job was at Ochsner LSU Health Shreveport in their Level 1 Trauma ICU, where I stayed for one year. After leaving, I went back to working in an ER at Heart Hospital of Austin in Austin, Texas, where I also stayed for a year.
Once I was introduced to my first flight crew, my goal was to work my way toward becoming a flight nurse. I first applied for flight jobs after completing two years of nursing. The first company to take a chance on me in flight was LifeNet Air in 2024, where I started strictly working fixed wing at LNA3 in Texarkana for a year and then transitioned to rotor full time at LNA4 in Daingerfield, TX. I later came back to LNA3 as base manager in October 2025, and in April 2026, I also stepped into the role of base manager for LNA1. I have also been accepted to Louisiana State University to begin my bachelor’s degree in business Analytics.
In my free time, I enjoy playing golf and spending time outdoors, especially hunting and fishing. I also enjoy spending time with family and friends, often over a good meal.
