National Matching Service
National Matching Services (NMS) specializes in the development and administration of Matching Programs. NMS was founded in 1985, after developing sophisticated matching algorithms and software for the placement of physicians into residencies in the US. Since then, NMS has implemented Matching Programs in a number of industries and professions, including osteopathic medicine, psychology, dentistry, pharmacy, and optometry.
