The Code of Ethics of Sigma Phi Delta is founded upon the basic principles of truth and honesty. The quotation, "Whatsoever things are true, whatsoever things are honest," should be the light guiding the footsteps of an Engineer towards service and success.
An Engineer should at all times be mentally, physically, and morally clean, and should conduct himself as a gentleman. He should be courageous in following his own convictions, mentally awake to make use of every opportunity, and should consider the welfare of other before his own.
To his superiors, an Engineer should be dutiful; to his co-workers, helpful; to his subordinates, generous; to all men, brotherly.
An Engineer should take a good grip on the joys of life. He should play the game like a man. He should fight against nothing so hard as his own weaknesses, and should endeavor to gain in strength.
He should live that his actions shall never besmirch his own honor, and thus maintain the honor of the Engineering Profession.

The Object of Sigma Phi Delta shall be to promote the advancement of the Engineering Profession;
to foster the advancement of Engineering Education;
to instill a greater spirit of cooperation among Engineering student and organizations;
to inculcate in its members the highest ideals of Virtuous manhood, good citizenship, obedience to Law, and Brotherhood;
and to encourage excellence in Scholarship.

According to Wikipedia:

"Eta Chapter has the largest number of registered alumni in the entire Sigma Phi Delta Organization, with over 900 living alumni worldwide."

Our Alumni provide an amazing network for networking and career advancement. They have also contributed to the stability of our fraternity as it experienced successes and struggles.

We have our alumni to thank for the beautiful Haggerty House that houses the majority of our fraternity's members as well as our events and meetings. The house is located at 910 North Renee St., just north of Marquette's Campus Town apartments and academic campus.
