Located on the northwestern side of Lincolnton, the original campus consisted of a large frame house nestled in an oak grove near the banks of the South Fork River. The stated mission of Fassifern was "to prepare girls for the best colleges, or to be self-supporting, and to help them become lovers of the best in literature, music, and art." Assisted by her sister and an able faculty, Shipp operated the school much like a Christian home, with a heavy emphasis on academics, religious and physical training, and self-discipline.
Students came from throughout North Carolina as well as other states, and Fassifern gained a reputation as one of the South's best preparatory schools. Despite an addition to the physical plant, the Lincolnton facility quickly became inadequate for an ever-increasing enrollment.
Enticed by an offer from a group of businessmen from Hendersonville, Shipp moved the institution to that mountain town in 1914. On its spacious new campus highlighted by colonial-style architecture, the school continued to grow and prosper under the tutelage of "Miss Kate."
Soon after her sister died in 1924, Shipp sold Fassifern to Joseph R. Sevier, a Presbyterian minister. Sevier and his son John successfully operated the school for a quarter of a century. Fassifern School continued operation on the Hendersonville campus until 1951, when John Sevier moved to Atlanta to accept a position with Southern Airways.
