Men of Honor Since 1850

Phi Kappa Sigma (ΦΚΣ) is an international all-male college secret and social fraternity. Its members are known as "Phi Kaps", "Skulls" and sometimes "Skullhouse", the latter two because of the skull and crossbones on the Fraternity's badge and coat of arms. Phi Kappa Sigma was founded by Dr. Samuel Brown Wylie Mitchell at the University of Pennsylvania. Mitchell recorded the initial ideas and concepts of Phi Kappa Sigma on August 16, 1850. He then began to discuss the idea with other students, first Charles Hare Hutchinson, and then Alfred Victor du Pont (son of Alfred V. du Pont), John Thorne Stone, Andrew Adams Ripka, James Bayard Hodge, and Duane Williams. The seven men formally founded the Fraternity on October 19, 1850 becoming the founding fathers of Phi Kappa Sigma.

Mission and Vision


The vision of Phi Kappa Sigma is a simple one:

We will strive for lifelong growth and development of the Fraternity and its members.

Phi Kaps are not complacent, and are unafraid to continually raise the bar for themselves. When you spend a few minutes talking to a Phi Kap, you will realize that he is never willing to settle, is never satisfied, and always wants to push forward. As one of the oldest and forward-thinking fraternities in existence today, Phi Kaps have spent 150 years showing the rest of the fraternal world how it’s done.

Core Values

Trust, the foundation of a relationship based on a belief in oneself as well as others, which is earned and strengthened through experience.
Honor, staying true to a set of higher standards and morals in the face of adversity. Membership in Phi Kappa Sigma means a commitment to leading an honorable life.
Respect, which begins with yourself and the practice of the golden rule, "Do unto others as you would have them do unto you."
Knowledge, the acquisition of thought, theory and principles following in the footsteps of our founding fathers in accordance with our oath of brotherhood.
Wisdom, a virtue gained through experiences of self and others. Wisdom is the application of knowledge and past experiences to make decisions regardless of the situation.
Responsibility, by being reliable in the fulfillment of the objectives of our Fraternity and our personal obligations, enduring the consequences of our actions.
Integrity, our inner foundation for holding true to our values of trust, honor, respect, knowledge, wisdom, and responsibility that guides us to make the best decisions.
