I graduated from George Mason University with a degree in Integrative Studies, and my concentration was Leadership Studies. I went throught the New Century College of the University and highly recommend their programs. The Dean of the school, Nance Lucas, and their Leadership Coordinator, Heather Hare, are both very involved with the students. I believe the university also offers a Certificate in the program of study if you didn’t wish to complete the entire 30 credit program.
Hope this helps!
