Current out-of-the-hospital activities include eating at Philadelphia's fabulous BYOB's with husband Sean at a ridiculously early time, acquiring baby sitter for said dinner, hiding her son's pacifier as she attempts to wean him from it, teaching her daughter about early 90's fashion and TV shows, and phone conversations with her large extended Jamaican family who always remind her that academic medicine is great, but that making an Olympic track team would be even better.

Oana Tomescu Many people wonder whether Oana (oh-ah-nah) hails from somewhere exotic like Hawaii, Tahiti or Bali; but she does not. With a last name like Tomescu (Toe-mess-Q), she was, of course, born in (un-exotic) Romania and came to the States at age 7, after her parents defected. She grew up in New York suburbia and went to college in Boston suburbia. Moving to urban Philly for med school was quite transformative and she’s lived in almost every section of the city. Professionally, Oana trained in primary care Internal Medicine (here at Penn) and pursued a fellowship in Adolescent Medicine (here at CHOP). Despite the fact that she is technically not Med/Peds, she is still allowed to hang out with the group and is one of the Associate Program Directors. She sees patients at both HUP and CHOP, and oversees the general curriculum and outpatient Internal Medicine clinic for the program. Personally, she lives in NJ suburbia and has 1 husband, 2 teenage step-sons, 2 dogs and 1 cat. She loves sports of all kinds: she played volleyball for her college and for some time afterwards, but a career-ending (ha!) ACL tear lead her to study Baptiste Power and Ashtanga Vinvasa yoga. She is currently curious about mind body healing and gardening.

Dr. Chadwick Johr is a pediatrician, general internist, rheumatologist, and all-around-enjoyer of medical education. I went to Penn state for medical school and Brown for residency. After residency I was a hospitalist at CHOP for a year and then moved to the University of Iowa for rheumatology fellowship. After fellowship I stayed on as a member of the faculty and attended on the medicine wards, peds wards, rheum consult service, rheum clinic and in the newborn nursery. After a four-year Midwestern hiatus, I decided to come home to Philadelphia. Now I spend my days seeing rheum patients, attending on the wards at Presbyterian Hospital, and supporting our med peds residents. My interests outside of a love of medicine and teaching: exercise (running, ultimate Frisbee, racquetball), music (guitar, indie rock), food (eating, not cooking), board-games (very nerdy, very proud), language (Spanish and maybe 5 others before I die), self-improvement (tireless in my pursuit to do everything better.)


Parker Hudson: Parker is a tall, but gentle giant. He was born in Charleston, SC and grew up in Atlanta, GA. He attended University of Georgia in Athens where he miraculously survived the glory days with grades that allowed him to attend medical school. During his undergraduate years, he took a semester off of school to volunteer as a teacher in a rural village in Ghana, West Africa. He also cooked in various restaurants (and considered culinary school) and played ultimate frisbee for Jojah. After college he spent several months out West backpacking and completing a wilderness-EMT course before moving to Philadelphia to do research at CHOP. The following year he began medical school at Penn Med. He stayed for the med/peds program, because he was impressed by the strength of the residents, the quality of the education, and the appeal of the Global Health track. He has been to Botswana twice and is looking forward to his next two trips there. Professionally, Parker wants to combine his med/peds training to care for patients of all ages with HIV both here and abroad. Personally, he recently married his med school sweetheart. He enjoys cooking for his wife, who might starve without him, and stays active running, cycling, practicing yoga, flyfishing, traveling, and reading the Economist. He is currently learning to sail and scuba dive to keep up with his hydrophilic wife.
