A message from the chairman

Dear Colleague:

Thanks for your interest in the Internal Medicine Residency Program at Geisinger Medical Center. Our tradition of excellence in residency training continues as we train you, our physician leaders of the future.

With this multidimensional approach to education, you’ll get a broad range of experiences in a supportive environment. Inpatient rounds, didactic presentations and multidisciplinary team conferences help you understand your patient’s health in a broader context. At Geisinger, care is empathic, evidence-based and collaborative — and you’ll learn a lot from our talented and dedicated faculty.

During residency training, you’ll grow personally and professionally as you develop your skills as a physician, in part due to mentorship and learning opportunities. Once you’ve completed your residency, we’re confident you’ll thrive in any clinical environment.

The Medicine Institute is actively engaged in clinical research. Each department in the institute has ongoing clinical projects, and we encourage you to participate. Every year, staff, residents and fellows publish their work in peer-reviewed journals and present their work at regional and national meetings.

So, why Geisinger? Providers know that we’re recognized nationally as a leader in enhancing care through innovation, quality and applied technology. Our integrated clinical practice model includes precision medicine and clinical genomics, machine learning with artificial intelligence and the use of big data to improve population health and chronic disease conditions. And patients know they’ll get top-notch care from a company that’s been in their community for more than a century.

We’re excited to welcome the next class of internal medicine residents to our Geisinger family. I hope you come with curiosity and eagerness to begin an exciting and meaningful career in medicine. We look forward to supporting you in that journey.
