Alpha Sigma Kappa began at the University of Minnesota as a little sister organization to Triangle Fraternity called the Sisters of Triangle. On May 1, 1989 the members of this little sister group decided they wanted a stronger, more unified group and decided to form a local sorority for women in engineering, mathematics, sciences and architecture.

On May 1, 1996, the sisters of Alpha Sigma Kappa ratified the National Constitution. Later that year in early August, they held their first National Convention at which they accepted the petition for colonization of an interest group at the University of Oklahoma. The colony received their charter a year later in September 1997, making them the second chapter of Alpha Sigma Kappa.

Since then Alpha Sigma Kappa has continued to grow. Our sisterhood has over 300 initiated memebers, six active chapters, five alumnae chapters.
