About Princeton Medical Institute

Providing Innovative Mental Health Treatment

Princeton Medical Institute (PMI) is the headquarters of Global Medical Institutes, LLC, an investigative research organization that has been conducting clinical trials in the areas of psychiatry, neurology, and general medicine since 1989.


Our 12,000 square foot facility is staffed with experienced clinical research professionals, including board-certified physicians and registered nurses. Since our site opened in 1991, we have enrolled over 5,000 patients in over 500 clinical research trials. We work in conjunction with pharmaceutical companies to conduct research studies that determine the safety and effectiveness of investigative medication for a wide range of illnesses and conditions.


We are conveniently located in Central New Jersey, just a few miles from Princeton University. We are active members of the Alzheimer’s Association. PMI is the only New Jersey site included in the Global Alzheimer’s Platform (GAP), which promotes advancing Alzheimer’s disease medications from the laboratory all the way through clinical research trials.
