The first school of chiropractic opened in 1897, two years after D.D. Palmer performed his first chiropractic adjustment.
Chancellor and CEO Dennis Marchiori says the college is a key contributor to the local economy, with 42 million dollars a year in payroll and purchasing, and 20 million spent by its students.
"Because of our students not coming from the Quad Cities region, all of our students for the most part other than a few exceptions, come from outside of the Quad Cities. Then because of that we're really bringing those resources into the Quad Cities that otherwise wouldn't be there."
The college has also spent millions in recent years improving the campus, opening a new student clinic, student union, classrooms and labs, and student housing.
"It's the oldest campus in chiropractic and at the same time, thanks to the work over the last ten years, it's actually the most modern campus in chiropractic eduation of the 18 programs in the US."
Since its founding, Palmer has opened branch campuses in California and Florida, and together they have 31,000 living alumni.
Dr. Marchiori expects about 2,000 former students and friends will be in town this weekend for the anniversary celebration.
