Logan College of Chiropractic 1851 Schoettler Rd, Chesterfield, MO63017 Logan College is the second oldest chiropractic school in the United States. Classes are conducted on a trimester system…More with rolling admissions. Students complete four trimesters of science courses. They spend one trimester in the student clinic, where they work on other students. Their last trimesters are spent working in the outpatient clinic on campus. By the time students graduate, they will have spent 5,000 hours with patients and taken 300 credit hours of classes. About 10 percent of those classes are business-related, so students are equipped to start their own chiropractic office upon graduation. The school has a recently renovated student center and a library with more than 12,000 books, and group study rooms. The Purser Center is also on its campus; many concerts and other events are held there. For more information, see the school's website.
