“I chose Cincinnati Children's because of how much residents are valued throughout the hospital. Resident education, wellness, and personal growth are top priorities at Cincinnati Children's. I believe this commitment to residents allows us to focus on optimal care for the patients.” Meredith Harris, MD, PL-1 Categorical Resident

“I chose Cincinnati Children’s because, while it offered all the elements of a superb program with respect to teaching, research and other ample opportunities, it also stood out from other programs which possessed similar qualities. The enthusiasm and energy of the residents was palpable and the faculty and staff seemed genuinely dedicated to fostering a welcoming, healthy and stimulating learning environment. I felt Cincinnati Children’s would simultaneously challenge and nurture me to become a great pediatrician while allowing me to pursue my passions. I left my interview wanting to belong to their inspiring community. And if that wasn’t enough, the cups music video we saw on interview day sealed the deal!” Sarah de Loizaga Carney, MD, PL-2, Categorical Resident

“The most important reason I chose Cincinnati for residency was the people I met while interviewing. Everyone here looks out for one another; this is a culture that is difficult to find anywhere else in the country, especially at a large academic center. This aspect of the residency was enough to pull me away from my family for three years and potentially longer. The second reason that drew me to Cincinnati was the strength in the research programs. As an MD/PhD, I needed to find a place where I could obtain the best clinical pediatrics training possible, while still offering the opportunity to remain involved in research as I traverse my years of residency and fellowship. The program administrators go so far as to recommend mentors and set up introductions with whomever, whenever possible. This made finding the right people and the right project extremely easy. One of the final reasons I chose Cincinnati Children's were the intangibles, the overwhelmingly positive feelings I experienced at my first visit. I knew I would be happiest matching here and I was lucky enough to see that come to fruition.” Benjamin S. Mantell, MD, PhD, PL-3, Categorical Resident
