The College of Osteopathic Medicine of the Pacific (COMP) was founded in 1977 in Pomona, Calif. It developed into Western University of Health Sciences in 1996 and today consists of nine graduate colleges: COMP, allied health professions, graduate nursing, pharmacy, veterinary medicine, dental medicine, optometry, podiatry and biomedical sciences.

Some 3,572 physicians have graduated from the university in the last 31 years.

Since 2004, the university has sponsored a Northwest Track, in which 30 students study for two years on the Pomona campus and then complete their clinical rotations in the Pacific Northwest.
