Celina completed her undergraduate degree at California State University, Chico in May of 1996.

She moved to Gainesville, FL to pursue a M.S. degree in animal science and coach the University of Florida Livestock Judging team. During her tenure at the University of Florida, she assisted with various youth livestock programs and assisted with many undergraduate animal science courses. Upon completion of her M.S. degree, she transferred to Oklahoma State University to complete a Ph.D. in animal nutrition. At Oklahoma State University, she developed an interactive applied animal nutrition webpage and assisted with youth livestock activities and her research focused on applied beef cattle nutrition. In July of 2005, she joined the faculty at California State University, Chico in the College of Agriculture.
