Our Zeta Pi Chapter marked its 40th anniversary on March 15, 2026.
With that anniversary came our annual Orchid Ball event the Friday before at the San Marino Club in Troy, Mi.
We had a strong active and alumni presence, with 80 Brothers and a total of 140 people attending this milestone event. This ranged from Founding Fathers to current and prospective members, 2 new recipients of our Chapter’s Founders’ Awards, the Sigma Pi Grand Sage, amazing women, and quite a bit of history on display.
