Under Mr. Tieman's direction, Caron provides an extensive continuum of care for teens, young adults, adults, older adults and families at its facilities in Pennsylvania and Florida and its Regional Recovery Centers in Atlanta, Ga., Philadelphia, Pa., New York City, New England., and Washington, DC.  Also under Mr. Tieman, Caron has taken leadership roles in sponsoring research in addiction treatments and outcomes and advocating for ethics and standards and participating in national conferences on addiction and recovery. Since Mr. Tieman joined Caron, its revenue has grown ten-fold, making it one of the largest nonprofit residential addiction treatment centers in the nation.

Mr. Tieman believes that research and prevention are key to resolving the addiction crisis. Therefore, Caron participates in studies with leading research universities including the University of Pennsylvania, Thomas Jefferson University, Brown University, and Treatment Research Institute, and conducts on-campus training for physicians and other health care professionals, including being the only freestanding addiction treatment center to offer a fellowship in Addiction Medicine. In addition, Caron's Student Assistance Professionals work on alcohol and drug prevention in 700 schools.

Mr. Tieman has spent more than 30 years in the addiction treatment field in treatment center and industry leadership positions. Long an advocate for patient-centered care, he has authored several articles and blogs on the issue of patient’s rights and called for the implementation of standards and outcomes-based treatment in the addiction treatment sector. Most recently, Mr. Tieman testified before the House Energy and Commerce Committee’s Oversight and Investigations Subcommittee on the issue of patient brokering and fraud in the addiction treatment sector.  Under his direction, Caron adopted the Addiction Treatment Patient’s Bill of Rights and is working with other national centers to improve the standard of care for those struggling with the chronic, treatable disease of addiction. 

Mr. Tieman began his career with the Hazelden Foundation and has served as Chairman of the National Association of Addiction Treatment Providers, a member of the American College of Addiction Treatment Administrators.  He is currently a Board Member of the American Foundation for Addiction Research.

Following undergraduate degrees from both Concordia and Northwood Universities, Mr. Tieman completed the Minnesota Management Institute at the University of Minnesota and received an Honorary Doctor of Laws degree from Concordia University.
