Markus Beissinger ’13

“The group of guys Sigma Nu attracts are hardworking, honest, honorable, and giving. All the guys I met there will give very selflessly to other people and help out no matter what. It makes me proud to be associated with that type of person.”

We caught up with entrepreneur and recent graduate, Markus Beissinger ’13, who has made strong bonds with his brothers, and despite living in San Francisco, he continues to keep in touch. Though he’s new to the alumni experience, he feels a sense of gratitude for the alumni support during his time at the chapter and hopes to one day give back to the chapter, just as those before him did.
