Outside of work they enjoy drawing and jewelry making.

Student Employees

The planetarium strives to hire student workers to help run the day-to-day operations of the lobby and dome theater. We employee both STEM and non-STEM students, utilizing their strengths to not only add to the success of the planetarium, but be a place where they can grow professionally.

Presenters

Presenters lead field trips for K-12 students and deliver public shows for curious visitors, sharing their passion for astronomy. They also help manage the dome, write show scripts, and operate telescopes.

Christian Jeffreys

Christian is a current student here at OCC, studying Communication in order to transfer into the
University of California system. He grew up in Dallas, Tx, and has been living in California for 4 years. He
found his interest in space when he was a child, looking up and wondering what mysteries fill our
cosmos. This curiosity led him to pursue a tangent of terrestrial mysteries, becoming an avid
naturalist and explorer. He commonly finds himself out in the great outdoors, exploring the beauty
that our world has to offer. His hope is to relay that curiosity to our youth, leading him to pursue
roles in education after his studies.

Federal Work-Study

Federal Work-Study, also referred to as FWS, is one of the three major federal student aid programs from the U.S. Department of Education. It is designed to provide part-time employment to students who have established significant financial need according to federal guidelines. The federal government pays a percentage of the student's salary; the school pays the remainder. FWS is part of the total financial aid package and is not intended to be the sole source of assistance. Many students either seek a position related to their career objective or seek positions that offer skill development. In either case, the FWS Program is intended to provide a balance between the interests of the student and the needs of the department.

In order to qualify, you must:

1. Complete your FAFSA application
2. You must accept your federal work-study award upon receiving
3. Must complete an online employment application
   • Include any employment or volunteer history you have
   • Award Letter confirming you have been awarded FWS for 2025-2026
   • Class schedule must be attached to the application
