Dear Mission Family:
Thank you for choosing Mission! At SGMHS we are more than a school, we are a family. This section includes general information to help manage your experience as a parent/guardian. If you have any questions please contact us at sgmhs@missionpioneers.org or call (626) 282-3181.





Dear Mission Families,

Please take a moment to read the following update from the Archdiocese regarding the Coronavirus.  Though the threat remains low in the United States we are doing our part to limit the spread of illness.  The main request is that if your daughter has a cold or flu you need to keep her home. Thank you for helping us with this request.  We will continue to keep you updated on any further developments.

Many Blessings,

Ms. Raquel Cagigas, M.A., M.A., '96


Queridas familias de Mission:

Tómese un momento para leer la siguiente actualización de la Arquidiócesis sobre el Coronavirus. Aunque la amenaza sigue siendo baja en los Estados Unidos, estamos haciendo nuestra parte para limitar la propagación de la enfermedad. La solicitud principal es que si su hija tiene un resfriado o gripe, debe mantenerla en casa. Gracias por ayudarnos con esta solicitud. Continuaremos manteniéndolo actualizado sobre cualquier otro desarrollo.

Muchas bendiciones, 
Ms. Raquel Cagigas, M.A., M.A., '96

Students (and parents) should do all in their power to guard against absence from classes.  A Parent/Guardian (not the student) should notify the school Attendance Office on the day of the absence.  Messages may be left on voice mail 24 hours a day. 

To Report an Absence/Tardy:

  1. Call the Front Office to report the absence/tardy by 9am.
  2. State law requires a note signed by a parent/guardian for every absence.  This is due to the Front Office on the day of her return by 8am.

Same Day Early Dismissal:  Parents must send a note with your daughter to the Front Office by 8am.

Appointments: Verification is needed from a doctor, dentist, orthodontist, court, DMV, college appointments, etc. upon return to school.

At San Gabriel Mission High School we pride ourselves on communication and do all we can to be in touch with our families and keep them informed. Every week a phone call goes out with important announcements regarding school functions, reminders about upcoming events, and other school news. This phone call can be directed to any land line or cell phone; it can also be delivered via email. It is a great way to stay in contact with our families and help them be informed members of our community.

If you are not receiving our notification calls and emails please let us know at sgmhs@missionpioneers.org 

Attending a school like Mission with a smaller student body allows better communication between teachers, parents, and students.  Our teachers are dedicated to ensuring that each student is receiving the attention they need.  To strengthen this communication, each of our faculty and staff members is provided with a school email they can use to contact parents and students.  Their email address can be found on their staff page.  
Parents are welcome to contact their daughters teacher to schedule a meeting or to discuss assignments and grades.
Students can contact their teachers outside of school hours via email or class apps.
