The Pfeiffer Treatment Center, the medical clinic of the Health Research Institute (HRI), is staffed by a team of physicians, practitioners, chemists, and other professionals who specialize in the effects of biochemistry on behavior, thought, and mood. The on-site HRI Pharmacy compounds nutrients hormones, and other biochemicals to reduce the number of pills in a prescription using customized methods and equipment.

The Center was named in honor of Carl Pfeiffer, M.D., Ph.D., founder of the Princeton Bio Center in Skillman, N.J., and pioneer of biochemical therapy. Dr. Pfeiffer became interested in the research conducted at HRI and, before his death in 1988, worked extensively with the HRI team to share his knowledge of correcting the chemical imbalances.
