By 1900, there were 43 Baptist churches, 13 Methodist churches, three Presbyterian churches and four Episcopal churches in Henderson County.
Between 1900 and 1920 five additional Baptist churches are organized: East Flat Rock First Baptist Church, Balfour Baptist, Locust Grove Baptist in the Clear Creek community, Bob’s Creek Baptist in the Green River community, and Union Hill Baptist in the Dana community.
Two Methodist churches were organized during this period: Fruitland United Methodist Church and Etowah United Methodist Church.
In 1916, the first Lutheran church opened in the county, Grace Lutheran Church at the corner of Seventh Avenue West and Church Street. Today, Reformation Presbyterian Church meets in this historic building.
In 1910 members of the Seventh-day Adventist Church arrive in Henderson County. Arthur Spalding, Sydney Brownsberger and Martha Rumbough buy land on Howard Gap Road near the communities of Fletcher, Naples and Hooper’s Creek. Fletcher Seventh-day Adventist Church was the first church of this denomination to organize in the county.
In addition to beginning a farm, organizing a church and opening a school, they also began giving health care to local residents, mostly free of charge.
By 1915, the doctors formally opened a building (“cottage for sanitarium purposes”) to treat tuberculosis patients. Doctors and nurses were giving health care to local residents before they opened the tuberculosis cottage. After opening this cottage, they continued to give health care to residents.
The cottage that opened in 1915 grew quickly and by 1927 there were several buildings on the campus housing doctor offices and sanitarium and hospital facilities. The name was formally changed to Mountain Sanitarium and Hospital. People came from all over the nation to be treated for TB at the sanitarium.
The hospital served local residents, at little cost.
Fields of crops were grown on the property and local people were hired to work in the fields. The crops were used to supply food for the academy, the hospital and the sanitarium. They also established the first cafeteria in Asheville with the excess crops.
The hospital and sanitarium employed the first registered nurses in North Carolina in 1916.
By the early 1920s, a school of nursing for area women was built on the campus. This school was attended by hundreds of area women until 1984 when it closed. Many of the registered nurses employed by Patton and later Pardee Hospitals and area doctors were graduates of the Fletcher Hospital School of Nursing.
In 1976 the name was changed to Fletcher Hospital. Today it is known as Park Ridge Hospital.
The old hospital building is now being used as a nursing home and a new assisted living center was built on the campus.
A year after the beginning of the health care facilities in Naples, in 1911, a group of Hendersonville residents and doctors formed an association to open a hospital in the Hyman Heights section of Hendersonville. Patton Hospital opened in 1913. The 17-room hospital was built with private funds on land donated by Annie E. Patton. The hospital was staffed by five physicians with Dr. William R. Kirk as chief of staff.
After World War II, a drive began to build a new hospital. In 1953, the old Patton Hospital closed and Pardee Memorial Hospital opened at its current location on Fleming Street.
From 1917 to 1920, the worst world-wide flu epidemic in history swept through the county. Many people died; some entire families. Area cemeteries demonstrate the short lives of many young children  in rows of children’s graves. The total number of people who died in the county due to this epidemic is not known, but was most likely in the hundreds.
