Teacher and Substitute Teacher Appreciation Week is May 7-13, and LAUSD Daily is celebrating the classroom heroes who work every day to educate, lead, mentor and inspire the students of L.A. Unified. Each day this week, we will profile a teacher or substitute teacher selected by their Local District administrators as an example of the highly skilled and dedicated professionals who make up our teaching corps. Today, we feature Marianna Calvillo, a substitute teacher in Local District East; and Karen Gross Tomlin, a substitute teacher in Local District West.

Marianna Calvillo

Calvillo joined L.A. Unified’s Substitute Teacher Team in 2012. She already had worked for seven years as a teacher’s assistant at Sheridan Street Elementary School, where she gained valuable experience, respect for the art of teaching and a love of helping others. Calvillo has been lauded by her supervisors for her dedication, caring and “can-do” attitude.

“Ms. Calvillo is prepared to do whatever it takes to make sure her students excel,” said a principal at a Local District East school.

Calvillo plans to continue her life of service to youngsters, as either a speech-and-language pathologist or a full-time teacher. Either way, students will benefit from her continued dedication and commitment to doing for others.

Karen Gross Tomlin

Karen Gross Tomlin has been a valued member of the District’s Substitute Teacher team since 1976.

She attempted to retire in 2008, but returned just a month later after realizing that her heart belonged to her students. She has proven to be one of our best examples of what teaching is all about. She treats every classroom as her own. Principals talk about her unending passion, her professionalism and her incredible way with both students and all staff who come in contact with her.

Gross Tomlin is a Local District West substitute teacher by title, but her actions make her an unparalleled role model for both kids and adults alike.
