About Phi Delta Theta

The Pennsylvania Rho chapter of Phi Delta Theta was founded on October 26, 2013, making it still a very young and evolving chapter.

Our Mission

"Phi Delta Theta was built on three pillars that haven’t budged an inch since the Fraternity was founded by “The Immortal Six” way back in 1848 at Miami University. The pillars are: The cultivation of friendship among its members, the acquirement individually of a high degree of mental culture, and the attainment personally of a high standard of morality. Shortened, we refer to the principles as friendship, sound learning and rectitude.

Helping every individual to meet his true potential is the bedrock of the Phi Delta Theta Fraternity. By celebrating each person’s true self, and by learning from each other’s strengths while helping to improve each other’s weaknesses, every member of Phi Delta Theta develops into a greater version of himself than he could ever on his own. Rather than try to find young men to “mold” into some ideal, we celebrate the uniqueness of each individual and, through encouragement, values, example and brotherhood, empower every brother to exceed his personal expectations." - Phi Delta Theta GHQ

Our Commitment to Health & Safety

Above all else, our chapter (and the Fraternity at large) prioritizes the health and safety of its members. We truly believe in creating a society where every member can become the greatest version of himself, and for that to occur, every member needs to feel respected and supported by his Fraternity. For that reason, we are strictly against and do not tolerate hazing of any kind. Behavior like this holds no place in the Phi Delt experience.

In addition to this, we do our best to foster a positive environment where brothers can excel, and this includes both chapter facilites and the culture of our organization. Our fraternity house and chapter facilities are alcohol-free, and we take pride in having a clean and livable house. We also do a lot to cultivate a community where our members can speak their mind and seek help when they need it. Here are some of the ways we do this:

Phi Delta Theta has a national partnership with the LiveLikeLou Foundation. LiveLikeLou is a non-profit organization that spreads awareness about ALS, raises money for ALS research, and helps support ALS patients and their families. LiveLikeLou was founded by Neil Alexander, a former Phi, in 2012; unfortunately, Neil passed away from the disease in 2014. Both nationally and in our chapter, Phi Delta Theta honors the memories of our brothers Neil and Lou by joining the fight against ALS and doing our part to spread awareness, raise money, and help those who need it.
