About Me

Why I chose to pursue a career in medicine:

Coming from a family of physicians, I've always had an interest in biology and how remarkable the human body is. And although I majored in journalism in college, becoming a physician was always my career goal. I pursued Internal Medicine because I like working with adults, from adolescence to the elderly, sifting through multiple organ systems and problems. Primary care, in particular, is perfect for me because I love getting to know people over time, and in forming good partnerships to promote healthier lifestyles.


What I want my patients to know about me:

I have several philosophies as a primary care doctor. First, because we all have busy lives and schedules, I do try to keep my appointments on time. Second, I believe strongly in educating our future physicians, so I am proud to serve on WellSpan's faculty for our Internal Medicine residents and as clerkship director for visiting medical students from Drexel and Penn State. Finally, I practice standard evidence-based medicine, meaning I follow the guidelines put forth by the CDC, American College of Physicians, and the United States Preventative Task Force (USPSTF).


What I do when I'm not seeing patients:

Once all my “work work” is done, and all the laundry is cleaned and put away, I spend my free time with my toddler son outside in our yard or going for walks. In the summer time, I try to escape to the Jersey Shore. During the winter, my husband and I count down the days until spring training, when our beloved Phillies will hit the field yet again.
