  • In 1866, Seventh-day Adventists opened their first medical institution in Battle Creek, Michigan. Under the guidance of church founder, Ellen White, and leading Adventist physician, John Harvey Kellogg, the Western Health Reform Institute was established.
  • The institute gained an excellent reputation for using natural methods, the best of modern science and healthful living principles to treat and prevent disease. Notables like Henry Ford, John D. Rockefeller, Dale Carnegie, J.C. Penney and others came to Battle Creek to learn how to take care of their health.
  • What began at the institute, to a large degree, started a revolution in the diet, exercise and health care habits of thousands of Americans. The breakfast food industry began with Dr. Kellogg and the Western Health Reform Institute. Vegetarianism also was promoted as a way to live more healthfully.
  • In 1895, as more and more people moved west, the Boulder Sanitarium, now Avista Adventist Hospital, was opened. It was the third Adventist medical institution opened in the United States. Later, in 1930, Henry Porter, a Denver businessman, donated the money and land to open Porter Adventist Hospital.
  • In addition to those two original Colorado Adventist hospitals, two more were added in recent years: Littleton Adventist Hospital in 1989 and Parker Adventist Hospital in 2004.
  • In 1996, Centura Health was formed. This collaborative effort helped Catholic Health Charities and the Adventist hospitals of Colorado carry out their ministries more effectively.
  • In 2001, the four Adventist hospitals of Colorado became a member of Adventist Health System (AHS), which then became the Adventist sponsor to Centura Health.
  • AHS had its beginnings in 1907 with the establishment of Orlando's Florida Hospital. Since that time, AHS has grown to care for more than 4 million patients each year. AHS operates hospitals in Florida, the Midwest and Colorado and has become one of the largest protestant health care systems in the United States.
  • Currently, more than 600 health care facilities, worldwide, are affiliated with the Seventh-day Adventist Church. While more than 150 years have passed since Adventist health care began, the goal remains the same: to serve all members of the community with excellent and compassionate health care.
