    Geisinger Profile Doximity Profile

    “We’ve got that small-town feel, in a good way. It’s a safe place where neighbors still know each other, and that really benefits you as a provider because, at the end of the day, healthcare is about relationships.”

    • Internal Medicine
    • American Board of Internal Medicine
    • University of North Carolina at Chapel Hill School of Medicine Doctor of Medicine, 1999
    • Yale – New Haven Hospital Residency, 2003
    • Johns Hopkins Hospital Robert Wood Johnson Clinical Scholars Program Fellowship, 2006

    I joined Geisinger in 2006 because of our shared values. I’m passionate about improving transitions of care and Geisinger is constantly looking for ways to improve the status quo. It sounds simple, but facilitating communication and the plan of care across the continuum is not always done reliably in many healthcare settings. At Geisinger, we make it a priority.

    One of the aspects I love most about working here is the variety of opportunities, experiences and people that I care for every day. Our system spans the continuum of healthcare, from the time of birth, through the development of acute and chronic diseases, and we make a sincere effort to respect a patient’s choices at the end of life. There’s never an “average” day here, which appeals to the clinical, intellectual and business aspects of care in our evolving industry.

    People are always surprised by the size of our network. Our locations span the entire state of Pennsylvania. In the Northeast, we have a population of almost one million extended over a two to three county range. There is a place here for you regardless of what opportunities you want to pursue.

    We’ve got that small-town feel, in a good way. It’s a safe place where neighbors still know each other, and that really benefits you as a provider because, at the end of the day, healthcare is about relationships. When you think about how successful and happy you’re going to be over the course of your career, it comes down to the people you’re working with and the satisfaction you feel from providing good care. It’s why I’ve been here this long. I care about the people and the patients that I work with and serve.

    Walk through our doors and you’ll understand how genuine our entire staff is toward providing patient-centric care. We take a tremendous amount of pride in our community and it drives us to provide the best care. It’s palpable when you walk through the doors here at Geisinger.

    “We have a tremendous potential to impact large populations by conducting pilots that are scalable.”

    • Internal Medicine
    • American Board of Internal Medicine
    • Yale University School of Medicine Doctor of Medicine, 2010
    • Hospital of the University of Pennsylvania Residency, 2013

    Geisinger first came on my radar when I was in medical school at Yale and Don Berwick came to give Grand Rounds. Don was a leader in the quality movement from Harvard, and he was a big advocate for healthcare reform. He talked to us about the shortcomings in the model that many major academic centers followed, and he provided data on Geisinger as part of his argument that we could develop a superior approach to healthcare.

    Then, when I was doing my residency in Philadelphia, I began to see the limitations of the “hub and spoke” model Berwick had described, where many patients get their care at a major academic medical center, but often they do not receive care that does not fall within the focus of those institutions. I saw how limiting that was, because we were missing the opportunity to treat diseases at earlier, more treatable stages. In many cases, we provided academically rigorous care at late stages of illness, whereas many of these situations could have gone much better if patients had accessed quality medical care when they had better hope of a good outcome. Geisinger again came on my radar during residency because it was a well-known health system in Pennsylvania, and by this point people everywhere were talking about Geisinger’s unique integrated payer-provider approach to healthcare. I joined Geisinger immediately after I finished my residency, drawn by Geisinger’s reputation for innovation.

    Our patient population is diverse, with multiple platforms and clinics. We’re focusing on everyone from the well patient to the multi-morbid patient who needs the full resources of our system. Geisinger is creating innovative programs to meet the needs of our population, often in ways that would not fit into a traditional academic medical center’s business plan. As a primary care-internal medicine physician at one of our large hospitals, I have had the opportunity to be involved in many of these innovative programs and to see how impactful they are for our patients.

    “Our ability to innovate and drive healthcare change is a team effort. We believe in the idea of a "One Geisinger" mindset, which really enables us to come together and see a holistic picture of the impact we’re making.”

    • The University of Chicago Pritzker School of Medicine MD, Medicine
    • University of Chicago Law School JD, Law
    • Yale University BA, History

    President, Integrated Care Delivery – Humana

    Chief Medical Officer – University of Illinois Hospital and Health Science System

    Associate Medical Director – Kaiser Permanente

    Emergency Medicine Physician – Kaiser Permanente

    Expert Consultant and Advisor – U.S. government – Centers for Medicare and Medicaid Services

    White House Fellow – U.S. government – Department of Veterans Affairs

    Corporate Healthcare Attorney – McDermott Will & Emery LLP

    When my family first moved to Danville, we had a strong hunch that we would be just fine. But we never in our wildest dreams imagined how much we would like it here. With the low cost of living, the short commute times and the ease of getting your kids to and from extracurriculars, the overall day-to-day living is so easy. I call it the “Goldilocks Phenomenon.” The quality of life here is phenomenal. You can have the best of both worlds, because we’re only 2 ½ hours from the DC, Baltimore, Philadelphia and New York metropolitan areas.

    Geisinger’s positioning, geographically and in the industry, makes us a truly unique place to build a career with lasting impact. We’re democratizing world-class healthcare by delivering innovative programs to under-served populations in our communities. For example, with MyCode, we’re able to bring one of the preeminent genomics programs in the world to out-of-work coal workers in Pennsylvania. We’re also making tremendous strides in making care more accessible. Now, over 85% of urgent appointment demands in our primary care environment are seen the same day or next. And on the specialty level, we've been able to take a couple days off of the overall average days waited until someone gets seen. That is an astronomical degree of progress.

    Our ability to innovate and drive healthcare change is a team effort. We believe in the idea of a "One Geisinger" mindset, which really enables us to come together and see a holistic picture of the impact we’re making. This approach has made us an organization that's not just improving the care for our local communities, but is a model for the future of healthcare. As we look to the future, we’ll continue to invest in new and better ways to make healthcare more accessible.

    Geisinger Profile

    “The other unique part of Geisinger is the heritage in the community. Many of our patients come here because their family members came here and a lot of our staff have relatives who’ve worked here.”

    • Internal Medicine, American Board of Internal Medicine
    • Nephrology, American Board of Internal Medicine
    • Albert Einstein College of Medicine of Yeshiva University, Doctor of Medicine
    • Wilford Hall University S. A. F. Medical Center, Residency
    • Duke University Medical Center, Fellowship

    I started my medical career in the Air Force in the family practice residency at Wilford Hall University in San Antonio. I took a tremendous amount of pride caring for and educating the active duty and retiree population. That passion for teaching is something that I’ve carried with me my entire career, from Yeshiva University to my years on the Air Force base, to my bench research at Duke, and now as the Chief Medical Officer at Geisinger.

    I came to Geisinger in 1995 because they offered me an opportunity to teach within the internal medicine residency program and they had the quality of care that I was looking for. When I started, I was one of five nephrologists, and we’ve since developed it into an incredibly high-quality, nationally recognized program. We’ve built a team of innovative and exciting practitioners, including two clinical researchers. One has a K-award and the other one has an epicoriograph and is in the process of getting his second pecoric.

    We’ve always been at the forefront of value-based care, as one of the first health systems to implement EPIC and MyCode®, one of the first health system genome sequencing programs. We have a unique structure with the Geisinger Health Plan and the clinical enterprise, as well as the research department, and it allows us to move down that pathway and be at the cutting-edge from other institutes across the country.

    The other unique part of Geisinger is the heritage in the community. Many of our patients come here because their family members came here and a lot of our staff have relatives who’ve worked here.

    That heritage in the community means our patients are loyal and they trust us to provide them the highest quality care. For example, before the MyCode® process began, I was researching metabolic stone disease and the risk of patients for developing kidney stones. I began drawing blood off my patients and banking it for DNA. About 95% of my patients consented to this and wanted to be a part of the process, whereas other larger institutions were trying to do similar testing with only a 5–10% patient consent-response rate. I think it just underscores the level of respect and trust that Geisinger patients have for the system.
