Emily Roh
Emily Roh is an actress for Dr. Yulia Landa, aspiring to become a doctor. Though not an actress by profession, she had had done some work in voice acting that eventually grew into small-scale experiences in a local film and a health care commercial that she did while working in the public health field. She received her Masters in Public Health from Columbia University's Mailman School of Public Health after moving to New York from Bogota, Colombia in South America. After being raised in Philadelphia, going to college in Boston, and living in Bogota, her interest in big cities and people brought her NYC and, eventually, to a position at Weill Cornell.
