Chadwick Johr Dr. Chadwick Johr is a rheumatologist, general internist, pediatrician and enthusiast of medical education. He went to Penn State for medical school, Brown for residency, and the University of Iowa for fellowship, where he stayed for a few years prior to joining the faculty here at the University of Pennsylvania. Aside from supporting our med-peds residents, Chad enjoys attending on the general medicine wards and caring for rheumatology patients as a co-director of the Penn Sjogren’s Syndrome Center. He is also excited about building his new young adult rheumatology transitional clinic but has yet to give it a formal name since “YART clinic” just doesn’t sound quite right. When not teaching learners about the wonders of methotrexate, Chad can be found beating residents and fellows at various “euro-style” board games, running up and down the Schuylkill river trail, learning Turkish on his iPhone, playing guitar, and trying not to spend his life savings eating out at all of the ridiculously delicious restaurants Philadelphia has to offer.


Laura Dingfield Laura Dingfield is the 2013-2014 med-peds chief resident. She was born and raised in Michigan, and spent her early years playing tennis and perfecting her penmanship. She escaped the frigid cold to attend college at Vanderbilt University in Nashville, TN, where she majored in Molecular Biology and cultivated an appreciation for country music. She returned to the University of Michigan in Ann Arbor for medical school (Go Blue!), where she spent significant time with various campus and community service organizations, and performed research on disparities in healthcare. She decided to pursue residency in med-peds because she was drawn to caring for adolescents with chronic illnesses. She chose to complete her residency training at Penn and CHOP because of the strong clinical training offered in both medicine and pediatrics, the excellent faculty mentoring available, and the collegial atmosphere among the residents. After her chief year, Laura will be staying on as a fellow in Hospice and Palliative Medicine at Penn. She envisions an academic career in palliative care, and hopes to split her time between clinical care and research. In her free time, Laura enjoys running and playing tennis with her husband, Mark, cooking, traveling, and enjoying all of the delicious restaurants in Philadelphia.
