Mr. Tieman has been the president and CEO of Caron Treatment Centers since 1995. Under his 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’s guidance, Caron has taken leadership roles in sponsoring research in addiction treatments and outcomes, advocating for ethics and standards, and participating in national conferences on addiction and recovery. Since Mr. Tieman joined Caron, its revenue has grown tenfold, making it one of the largest nonprofit residential addiction treatment centers in the nation.

He 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’s Treatment Research Institute, Penn State College of Medicine/Hershey Medical Center, the National Institute on Drug Abuse at the National Institutes of Health, and Stanford University. Caron also conducts on-campus training for physicians and other health care professionals, including the only fellowship in addiction medicine offered by a freestanding addiction treatment center. In addition, Caron's student assistance professionals work on alcohol and drug prevention in more than 900 schools, providing programs and services to 120,000 students, 6,800 parents, and 8,000 professionals.

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 patients’ rights and called for the implementation of standards and outcomes-based treatment in the addiction treatment sector. Most recently, he 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 and a member of the American College of Addiction Treatment Administrators.

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. He is the recipient of several awards, including Berks County Chamber of Commerce’s "Large Business Person of the Year" in 2004 and Eastern Pennsylvania Business Journal’s "Spotlight Award" in 2005. In 2017, The Philadelphia Inquirer named Mr. Tieman an “Emerging Icon” for his work in advancing addiction treatment and research. Mr. Tieman is also an author, having published several treatment sector-related articles and the book Flying Over the Pigpen: Tried and True Leadership Lessons from Growing Up on a Farm.
