William Ketchum, MD
Medical School: Uniformed Services University
Hometown: Silver Spring, Maryland

Will completed a preliminary year at Walter Reed National Military Medical Center and subsequently joined Einstein as a categorical intern. “As someone who owes until the year 2041 to the Army, my main interest is being as complete a surgeon as possible by the time I graduate so I can be prepared for deployment and operating abroad.” Will does not plan to sub-specialize in surgery, as he believes in remaining a true general surgeon, able to adequately serve the soldiers under his care in any circumstance.

Will values work-life balance; he stays active by playing soccer, running (begrudgingly), and lifting weights. He mostly enjoys spending his free time with his wife, Elizabeth, and his two dogs, Chewie and Scout.

“My favorite part about living in Philadelphia is that it doesn’t feel overcrowded like your typical large city. Everything isn’t packed and stacked on top of itself. Despite the large population in the area, everything is spread out so you feel like you have some space to breathe. Einstein is a great place to to train because it keeps you out of your comfort zone just enough to force you to adapt and learn. It is not the type of place where your hand will be held through every step, and this forces you to take charge of your own learning and take on a large degree of responsibility for your patients early on. I’ve seen and worked in other surgery programs, and I find this aspect of the surgery program at Einstein to be extremely rare.”

In her free time, she enjoys reading, traveling, exploring new breweries, and learning new languages.

“Einstein has been the perfect mixture of academics and high-volume, hands-on surgical training that I was looking for when applying to residency. Everyone in our program is extremely supportive of any endeavor you choose, and they will move mountains to get you there. Philadelphia itself has been amazing – everyone is very friendly, the food is fantastic, and a great hike is only 10 minutes away at any point. I couldn’t have chosen a better program or location for my surgical residency.”

“For me, Philadelphia is the city that has everything you may need in one place. Not many cities have such rich historical heritage and architecture, top academic universities and medical centers, cozy old city with outstanding restaurants and a world-renowned orchestra. It is never a boring place. Over the years, Einstein truly became a home for me. My professional journey began here as a Nurse Extern, then a SICU RN and now a General Surgery resident, all at Einstein Medical Center. What makes this hospital so unique are the people that work here and the family-like culture.
