The OXS Network

Professional development, philanthropy, and real community for students across every major.

Where business-minded leaders and STEM students grow together.

Founded at Penn State in 2018, OXS exists to build professional confidence, create meaningful service impact, and connect members to a network of ambitious students and alumni. We believe the strongest teams are built at the intersection of disciplines.

Professional

Workshops and speakers that actually prepare you.

Resume reviews, mock interviews, networking conversations, and cross-industry insight built for both business and STEM majors.

Philanthropy

THON is central to who we are.

We fundraise, show up for families, and carry Penn State's FTK mission through the entire year.

Brotherhood

A chapter culture that feels personal.

From formal events to everyday support, the chapter is built around people who genuinely want to see each other win.
