The McAllister Building was originally a women’s residence hall. It has been renovated several times and now is the headquarters for the Math Department. McAllister also houses an interview center where students can participate in mock and real interviews. More than 250 companies recruit at Penn State each year, and many students take advantage of the Interview Center. University Park’s Post Office is also in McAllister Building.

Health and Human Development Building is home to the School of Nursing and parts of the College of Health and Human Development. Henderson building is adjacent to Health and Human Development and holds more of that college.
