The Midwest Association for Toxicology and Therapeutic Drug Monitoring, MATT, was conceptualized among interested colleagues during the symposia on Advances in Clinical and Forensic Toxicology (ACFT I) in Milwaukee, May 1994. Discussions continued during the organization for ACFT II. MATT was officially formed at a meeting during ACFT II, May 11, 1995 in Milwaukee, Wisconsin. MATT was formed by about 100 charter members in midwestern states including Indiana, Illinois, Michigan, Minnesota, Ohio, Wisconsin and others, and incorporated under the laws of the State of Ohio.


As an association focused on advancing the scientific, clinical, professional and educational aspects of Toxicology and Therapeutic Drug Monitoring (TDM), MATT provides a network for interested individuals in the Midwest. MATT membership includes professionals such as clinical and forensic toxicologists, medical technologists, pharmacologists, pathologists, physicians and clinical chemists. The educational components consist of meetings rotating throughout major Midwest cities. It is the intent that meeting locations will be readily accessible, by car, to most of the members. In addition, the membership receives a newsletter on a regular basis. MATT strives to advance the science, research, clinical services and education in various areas of Toxicology and Therapeutic Drug Monitoring.
