About us

Program highlights

Patients overcoming substance use disorder need compassionate providers with a broad range of knowledge that spans disciplines.

As a Geisinger Addiction Medicine fellow, you’ll train for one year at Geisinger Marworth Treatment Center, a nationally recognized addiction treatment program accredited by The Joint Commission on Accreditation of Healthcare Organizations.

Marworth — named Pennsylvania’s No. 1 addiction treatment center by Newsweek in 2023 and ranked among the top five facilities nationally — offers inpatient, outpatient, intensive outpatient and partial hospitalization programs. Licensed by the Pennsylvania Department of Health, Marworth is a 91-bed facility (21 detox and 70 rehab), staffed with full-time admissions professionals, certified recreation therapists and nutrition/dietary professionals, with 24-hour nursing coverage.

We use evidence-based treatments that keep pace with new developments in this constantly evolving field, and we’ll prepare you for lifelong learning and leadership.

Our Addiction Medicine Fellowship is open to board-certified or board-eligible physicians from virtually any specialty, and we’ll prepare you for the certification exam offered by the American Board of Addiction Medicine.

Join our team and be part of the solution to a national crisis, examining addiction medicine as a public health issue — and learning to care for each patient as an individual with a unique background and path to recovery.

Welcome from the chief

Addiction medicine is a subspecialty that has gained increasing recognition in the last two decades. The overdose crisis has made many aware of the need for treatment of patients who have long been stigmatized and neglected.

The fellowship at Geisinger was one of the very first to gain certification, both by the American Board of Addiction Medicine and by the Accreditation Council for Graduate Medical Education.

The roots of the fellowship are in the compassionate, evidence-based clinical care of the person who has a substance use disorder. Over time, there have been more diverse clinical experiences added to the training, as well as opportunities to participate in research and to gain exposure to policy making. Addiction medicine remains a career that has many different avenues to make large contributions, and an important theme of the fellowship training is opportunity to explore those avenues.

The fellowship faculty are people who have chosen this career because they are dedicated to this work, they love the care of the patients and the evolving science of the medicine. That love of the work shines through the teaching and the support available to the fellows. The graduates of this program make us all proud: Many have gone on to take lead clinical and administrative roles in large organizations, they have all passed the board exam, many continue to work for Geisinger and teach in the fellowship. The health of our nation is improved because of their work.

Program overview

As our Addiction Medicine fellow, you’ll gain experience in inpatient and outpatient settings, along with community-based clinics.

Thanks to our unique setting, which includes rural and urban areas, you’ll work with patients of all ages from diverse ethnic backgrounds who span all economic strata. In each of these venues, and with each population, you’ll learn how to explore the specifics of scientifically based problem-solving.

You’ll also have an elective rotation, which you’ll design in consultation with the program director to meet your specialty focus and learning goals. By the end of the program, you’ll be able to incorporate new and developing strategies — both pharmacologic and psychological — into your skill set and adapt as the field expands.

You’ll also pursue a variety of scholarly activities, including active participation in journal club, individual reading, conferences, didactic exercises and preparation of a poster or scientific paper.
