I only visited for a day as an admitted student, but I was really impressed by the quality and humility of the faculty and the students, as well as the hospitality and helpfulness of the staff. As an international student, I ended up choosing a different school in a more cosmopolitan city, but if I was an American, the Sanford School would have been a top contender!
DCID is doing a commendable job. Their course on project appraisal and risk management (PARM) is the best one. They have the best faculty and best teaching methodology
