Founded in 1846, Alpha Delta Phi is the oldest fraternity in continuous existence at the University of Michigan. Our chapter house at 556 South State Street has served as home to thousands of Alpha Delts over the years with new members joining our brotherhood every semester. The Peninsular Society’s mission is to help connect alumni to actives and the larger alumni brotherhood. Please continue visiting this site for updates on events, to pay your alumni dues or provide updated contact info so we can keep you informed on chapter and alumni activities. We also encourage alumni to stop by the chapter house whenever you are in Ann Arbor to socialize with the active brotherhood. Xaipe.
