Community Service

Servant leadership is an important part of who we are. Whether it be on campus or at home, we individually embody the values of Sigma Nu in our daily lives. As an organization, giving back to the community allows us to grow as servant leaders. We volunteer at a variety of organizations around Davis including: Grace Gardens, Habitat for Humanity, Yolo County Food Bank, Putah Creek, Hillel House, TROTR, and more.

Here at Sigma Nu, we strive to promote the welfare of others. Each quarter, we hold a philanthropy event to raise money for organizations aligned with our chapters' values. In 2016, twelve brothers raised and donated ~$14,000 to the Pathway Home in our annual philanthropy Trekking for the Troops.  They then embarked on a 110 mile trek to the summit of Mount Whitney to raise awareness of post-traumatic stress and traumatic brain injury suffered by one-third of soldiers returning from Iraq and Afghanistan.

Our other three philanthropies - Shenanigans (Fall), Sigma Noodles (Winter), Kappa Kickball, you Snuze you lose (Spring) - send proceeds to St. Judes, the Blair Fox Scholarship, and Camp Kesem. To learn more about our philanthropies, contact our Trekking for the Troops Chair Nathan Clark (, or our Philanthropy Chair Jeffrey Simpson (
